This problem seemed confined to mailboxes that were created in the old profile on my PPC-only based mac, but which i was attempting to use after copying over my mac user from the old mac to the new one. the problem appears to no longer occur with a newly created profile and migrating over the old mail to the new location. Reproducible: Always Steps to Reproduce: 1. open thunderbird 2. have a waiting email on the POP server 3. Get New messages for that mailbox Actual Results: crash Expected Results: mail should arrive without crashing i keep my mail in /Users/kirk/Mail/johndoe for my main inbox and /Users/kirk/Mail/cabinet for my 'Local Folders'. so, i was able to not lose any email by just creating a new profile, then pointing the new profile at the mail location i had established and re-starting thunderbird, causing all of the old email to show up. (i had to do this for four different accounts; it was crashing for every one.)

Please for crashes, always give the talkback crash id (<http://kb.mozillazine.org/Talkback>).

the actual system and program config HAS NOT BEEN ALTERED (exept update to 10.5.2.) for the last months, it worked for month's in this config. worked in osx 10.5.2.from day 0 until this morning without any hickup, suddenly it started hanging and crashing at each startup TB gets the last incoming email at the providers place, a request later to get new mail on the same account ceashes TB I can send mail from my first (provider) to my second account, but TB refuses to receive NEW mail send to the first account (provider's), gives only the incoming mail of yesterday. When asking to get new mail TB crashes. TB 2.0.0.9 OSX 10.5.2. (even re-istalled from combo updater, repair permissions)

i believe comment #2 (https://bugzilla.mozilla.org/show_bug.cgi?id=392490#c2) is not quite the same problem as that originally described in this issue. and while this issue is still marked UNCONFIRMED, i would have to guess that a] from a standpoint of reproducing it, the thing is straightforward if perhaps slightly tedious (create a profile on a PPC-based mac for a given email address, have some email waiting in the POP-folder for that profile, migrate the profile/user to an intel-based mac, and attempt to get the email) b] this bug will crash for everyone migrating a profile from an iBook G4 or older to a macBook, and that seems pretty drastic!

note: awaiting crash ids

unfortunately, i no longer have the PPC-based mac with which to create a thunderbird account to cause this behavior, and so i can no longer reproduce the crash ... nor the crash-IDs from talkback. sorry. but i think that the reproducible instructions (augmented by point [a] in comment #3) would allow someone with an interest in reproducing/fixing this ample details about how to make it happen.

doing => incomplete since there is nothing unique in comment 0 steps that anyone would be likely to recreate the problem. rudy Ver if you still have a problem that is not resolved by support - http://www.mozilla.org/support/thunderbird/ - please create a new bug.

well, given that this is not yet RESOLVED-VERIFIED, i am really hoping that someone in QA has the proper equipment to reproduce this. frankly, i think this would be a very common problem: anyone migrating from using thunderbird on from a somewhat older mac to a macBook or other newer mac is going to encounter these unexpected crashes. at least now that it is marked resolved, QA can properly test and move back into the "OPEN-CONFIRMED" category. whoever is in QA, please take this seriously.

Justdave, does this describe anything similar to your migrate situation? (In reply to comment #7) > frankly, i think this would be a very common problem: anyone migrating from > using thunderbird on from a somewhat older mac to a macBook or other newer mac > is going to encounter these unexpected crashes. I wouldn't assume that

Hmm, dunno. The old and new macs in my case were both Intel. The profile in question was indeed created on a PPC Mac (under Mac OS 8 on Netscape Communicator 4.x, in fact), but it moved successfully to Intel Macs later, via Mozilla Suite and then Thunderbird.

Dave, any change? wouldn't ask, except I'm altering the bug, so may as well ask

No. Fixed it at some point, but I don't remember how. That was months ago. :)

If this is indeed a common problem, I'm sure someone else will report it and be able to help us track it down ;)

i doubt it's as common as it might have been when the intel macs were first coming out. i would guess that, when this problem existed, those who (like me) were seeing the problem and finding their mail simply entirely gone and having to start from scratch won't all be as likely as me (a mac programmer who understood the endian difference) to know what they ran into, nor (like me, someone who saves their mail outside the normal thunderbird profile location) as able to retrieve it.
