DO you already tried http://kb.mozillazine.org/Safe_mode ? Do you get the Mozilla crash reporter after the crash ?

Yes, I tried safe mode and the result is exactly the same. Yes, I did get the crash report - visible details are shown above

We need the crash ID of the report. You can find the ID if you follow https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report#Accessing_crash_report_IDs_outside_of_Firefox (replace Firefox with Thunderbird in the path). Can you please also try a new profile : http://kb.mozillazine.org/Profile_Manager

There are several crash reports, one of them is Crash ID: bp-0d71f9e5-c481-499d-adba-000382100122 I have also tried a new profile, Thunderbird loaded, but crashed as soon as I copied the old profile data into the new profile directory

bienvenu@4604 225 rv = acctMgr->FindAccountForServer(localServer, getter_AddRefs(localAccount)); This returns NS_OK + nsnull 226 NS_ENSURE_SUCCESS(rv, rv); this is the wrong check 227 localAccount->GetKey(aRetVal); this is the crash. my tree isn't new enough to have this code.

#32 crash for 3.0.1. all during startup

(In reply to comment #7) > 226 NS_ENSURE_SUCCESS(rv, rv); > > this is the wrong check If that's the wrong check, what _should_ it be -- and why wasn't it changed in the proposed patch ?

We should be checking for errors; the check isn't wrong; we just need the additional check

I didn't want to hijack timeless' patch as I want to get that in for 3.0.2, but I will extend the bug - add a bit of documentation to indicate that FindAccountForServer may return null, so that callers can be aware if they look at the idl.

Both patches checked in: http://hg.mozilla.org/comm-central/rev/b353a7fb731d http://hg.mozilla.org/comm-central/rev/0c73bb841289

Comment on attachment 423322 [details] [diff] [review] proposal Low-risk obviously needed null-check patch. a=Standard8

Comment on attachment 424570 [details] [diff] [review] Document possible null return value. Might as well take the comment-only documentation as well.

Checked into 1.9.1 branch: http://hg.mozilla.org/releases/comm-1.9.1/rev/2f13551589e4 http://hg.mozilla.org/releases/comm-1.9.1/rev/7a0516ecad29

Wayne can you verify this one please ?

Is this one of those problem where they see the crash only once? Or, will reporter be able to verify problem is gone with newer build? ftp://ftp.mozilla.org/pub/thunderbird/nightly/latest-comm-1.9.1/

It crashes every time - I still can't user Thunderbird If you have a compiled Windows version, I can try it out for you !

(In reply to comment #20) > It crashes every time - I still can't user Thunderbird > If you have a compiled Windows version, I can try it out for you ! have a look in http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/3.0.2-candidates/build1/win32/

It works now, problem solved Many thanks
