Every day when I open Thunderbird, one of the newsgroups is missing from the list. I can subscribe to them again, and they are added to the bottom of the list, but the top one disappears each day. Reproducible: Always Steps to Reproduce: 1. Subscribe to newsgroups 2. Close Thunderbird at the end of the day 3. Open Thunderbird the next morning 4. Look at list of subscribed groups Actual Results: The top group is missing each morning. Expected Results: Keep the subscriptions. These groups managed to stay subscribed using Thunderbird 2.x, it's only since upgrading that they have been disappearing.

This WFM on Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2pre) Gecko/20100119 Lanikai/3.1a1pre. Does it also happens in -safe-mode (http://kb.mozillazine.org/Safe_mode) ? Anything in Tools -> Error console when this happens ?

The Error console doesn't show anything. Opening in safe mode after first opening in normal mode didn't trigger anything, but it only seems to happen once a day so I'll try opening first in safe mode tomorrow.

I have now upgraded to 3.0.1, and opening in Safe Mode shows the same problem - I closed it yesterday with 4 groups showing, opened in Safe Mode this morning and only three were left, the top one was unsubscribed.

Could you post the newsrc file for the relevant account?

(In reply to comment #5) > Could you post the newsrc file for the relevant account? You'll find this file in your profile (http://kb.mozillazine.org/Profile_folder_-_Thunderbird).

I could upload it, but it's 180MB so that might be an issue.

Your newsrc file is itself 180MB? It's the file that would be News/newsrc-<server name> or News/<server name>.rc--all of my newsrc files combine come out to be ~1.5KB.

Yes, all the others are a couple of kb, that one is huge, even bigger than the combined .dat files in the <server name> directory. I always have had that server download all messages for reference, maybe it was storing the old messages there in a previous version? Now that you've pointed this out I'm thinking that I should try just removing all traces of that server from my profile & start afresh. If this bug is just a response to dealing with a bad old .rc file it might not be worth dealing with. On the other hand, maybe there are other people with large .rc files who will be upgrading in the future. Either way, thanks for your help & I'll wait to see what you think before changing anything.

Why don't you post the first few KB?

Accounting is the name of one of the groups on the server. @vantage is also a group on the server, but I am unable to view that one in Thunderbird due to the leading "@" in the group name (see bug 411568, filed by me). In that bug I can subscribe to the @vantage group, but I never see any messages; since most of the .rc file seems to consist of these @vantage messages it might be part of the problem.

Well, at this point I would recommend blowing away your newsrc file. This will have the effect of clearing the subscribed newsgroups and the read status, though.

I agree, I'll blow it all away and start fresh. I guess I'm really an edge case. Thanks for all your help!

Sounds like bug 387339 (which is 3 years old). When TB cannot parse a line in the .newsrc file, it acts like the line is not there. It offers to subscribe (again) and adds a new line to the end of the .newsrc file, which also causes the newsgroup to appear to move to the end of the list of subscribed newsgroups. Hard to imagine why this bug cannot get fixed after 3 years...

(In reply to comment #14) > Sounds like bug 387339 (which is 3 years old). nelson, I don't see anything detailed about your .newsrc file in bug 387339. was your .newsrc also large? Or just "bad"? in which case, were you able to find that was bad? === This list is a bit wide, but there are other reports how newsgroups get lost https://bugzilla.mozilla.org/buglist.cgi?type1-0-0=anywordssubstr&short_desc=news%20&field0-0-0=short_desc&bug_severity=critical&bug_severity=major&bug_severity=normal&bug_severity=minor&resolution=---&query_format=advanced&value1-0-0=Unsub%20lost%20gone%20resub%20corrupt%20newsgroup&short_desc_type=allwordssubstr&type0-0-0=anywordssubstr&value0-0-0=subscription%20subscrib&field1-0-0=short_desc&product=MailNews%20Core&product=Thunderbird

I post a comment here because I want to confirm this bug also has occurred on my PC. Currently I'm using 3.1.10 version but I'm pretty sure this happened even to the previous one. Same story as Bobby Jones told here: a list of newsgroups subscribed, after a closed session the next one shows the same newsgroups less the top one and so on. User Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; it; rv:1.9.2.17) Gecko/20110414 Thunderbird/3.1.10. I'm using it on Windows Seven O.S. 64 bit.

Bobby, are you still seeing this issue? if you no longer see problem on newer release, please change resolution to WORKSFORME. if you do see the problem on newer release, please update the bug with details.

RESOLVED INCOMPLETE due to lack of response to previous comment. If you feel this change is in error, please respond to this bug with your reasons why.

FWIW, Exact symptoms are happening here in TB 15 and at least 14 before it.

My .rc file had one huge line listing many groups, followed by several short lines listing one group each. When I deleted that first line (of course, losing all the information it contained), this problem ceased.
