Status: RESOLVED DUPLICATE of bug 492662

(MailNews Core :: Database, defect)

Description

[Andrew Piziali]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.16) Gecko/20080715 Fedora/2.0.0.16-1.fc8 Firefox/2.0.0.16
Build Identifier: thunderbird-2.0.0.14-1.fc8

I recently enabled automatic folder compaction. When I selected a local mail folder and moved its single message to another mail folder, Thunderbird starting compacting the folder. It crashed with a segmentation fault. Since I was running it in debug mode using gdb(1) under script(1) in an attempt to document another bug, I have the gdb execution trace and back trace.

Reproducible: Always

Steps to Reproduce:
1. Empty /var/spool/mail/andy using program mail(1).
2. echo Body of test message 1. | mail -s 'Test 1' andy
3. Start Thunderbird in debug mode under script.
4. Select local mail folder: piziali.dv.org -> Inbox
5. Select message "Test 1"
6. Move message "Test 1" to Local Folders -> Received
7. Either auto-compaction kicks in and crashes or right-click piziali.dv.org -> Inbox and select "Compact Folder." Thunderbird segmentation faults.
Actual Results:  
Thunderbird segmentation faults.

Expected Results:  
Folder is compacted and Thunderbird remains running.

piziali.dv.org -> Inbox is a symbolic link to my system local mail folder /var/spool/mail/andy:

$ ls -l .thunderbird/ceb0nm10.default/Mail/piziali.dv.org/Inbox
lrwxrwxrwx 1 andy andy 20 2008-05-23 15:01 .thunderbird/ceb0nm10.default/Mail/piziali.dv.org/Inbox -> /var/spool/mail/andy

I am attaching the script/gdb output and back trace.

The July 22, 2008 attachment a trace with the segmentation fault induced by simply right clicking on the folder piziali.dv.org -> Inbox and selecting "Compact."  All available debuginfo packages were installed for use by the mozilla.org ftp copy of 2.0.0.14.

Comment 3

Attachment: Trace of "script -c thunderbird --debug" with debuginfo.

This trace is that of running "thunderbird --debug" with all debuginfo packages installed.

Comment 4

Attachment: Trace of "script -c thunderbird --debug" using Fedora 8 TB.

I think this trace is much more useful than the previous two because the back trace includes all symbols in the stack, obtained from the debuginfo packages associated with thunderbird-2.0.0.14-1.fc8.  The seg fault was triggered by starting Thunderbird and right clicking on piziali.dv.org -> Inbox and selecting "Compact."

Andrew, can you reproduce using beta of version 3?

backup your profile before using

TB 3 beta 4 protects against a null db there, so I would bet it's fixed, and this is a dup.

Comment 7

[Andrew Piziali]

I ran the thunderbird-2.0.0.14-1.fc8 failure scenario against 3.0b4 and it did not seg fault. I am currently running Fedora Core 8, kernel 2.6.26.8.

Thanks for asking!

though I don't think this is fixed in the 2.0x code base, it is fixed in tb 3.
