Status: RESOLVED INCOMPLETE

(Thunderbird :: Folder and Message Lists, defect)

Description

[Darren Hart]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.13) Gecko/20101206 Ubuntu/10.10 (maverick) Firefox/3.6.13
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.13) Gecko/20101208 Lightning/1.0b2 Thunderbird/3.1.7

I run a local IMAP mail server (Dovecot). When I click on a large folder, thunderbird will crash (every time). I can use another client (evolution) and read the mail in the folder, sometimes after doing this Thunderbird will be able to view the folder. The folder structure looks like:

Dovecot
  Inbox
  Drafts
  ...
  Lists
    linux-embedded
    linux-kernel

Clicking on linux-kernel crashes. The status bar says something about downloading 1 of 4000 message headers when it crashes. The folder is listed as having 8120 unread messages.

No crash reporter starts. Running for the terminal just reports:
$ thunderbird 
/usr/lib/thunderbird-3.1.7/run-mozilla.sh: line 131: 17842 Segmentation fault      "$prog" ${1+"$@"}



Reproducible: Always

Steps to Reproduce:
1. Start Thunderbird
2. Click on the folder

Actual Results:  
The window disappears. When run from a shell, a Segmentation Fault is reported.

Expected Results:  
The message list should be displayed, and it shouldn't crash :-)

Is Lists/linux-kernel offline-use=on folder? (Folder Properties/Synchronization)
If yes, auto-sync works, and whole mail data of all mails is downloaded by "fetch body[]" after fetch of headers.
Can you you check with offline-use=off?
If offline-use=off, Tb doesn't request mail data after fetch of headers. Mail data is downloaded when you click mail, and required part only is fetched by "fetch body[N]" if needed instead of whole mail data download by "fetch body[]".
(1) Change to offline-use=off
(2) Folder Properties/General, Repair Folder
    => header of all mails is re-downloaded

1) Offline-use was off (I don't use it anywhere as this is a local IMAP server).
2) Repair fixed it. After a few minutes rebuilding the index I am able to view the folder again.

I guess you don't have any stack traces...so there's not much we can with this w/o the .msf file that caused the problem. It's possible this is fixed on the trunk.

I don't have any traces - a quick attempt to run in gdb failed. If I hit this again, I'll look for the documentation and get a proper trace. The msf is only 23MB, so if it happens again, I should be able to make that available as well. It's all mailing list data, so nothing private there.
