[Bug 93091] tunderbird crashes after startup in 06.06 (3 pane window shown for a second)

[Gregor Zattler]

Public bug reported:

Binary package hint: mozilla-thunderbird

Thunderbird segmentation faults after startup (3 pane window shown for a
second, then crash)

This is on Ubuntu 6/06 with
mozilla-thunderbird:
  Installed: 1.5.0.10-0ubuntu0.6.06
  Candidate: 1.5.0.10-0ubuntu0.6.06

Since this happened after a upgrade on 2007-03-10 with dozens of
packages upgraded (round about 4-6 weeks worth of an update) *and* the
problem remains even if downgrading thunderbird to 1.5.9 I think the
problem is related to another updated package.  I would like to attach
{s,l}traces but have trouble with launchpad.  If I'm not able to attach
the files I will email them to John Vivirito.


1.
my bug has nothing to do with corrupt profile since every time I reproduce it here I rm -rf /home/grfz/.mozilla-tunderbird


2.
my bug has nothing to do with a extension or theme which causes the crash since it also happens if I deinstall the only extension I use: mozilla enigmail. For the following examples I purged it again.


3.
I followed the procedure described in
https://wiki.ubuntu.com/DebuggingProgramCrash8, section "Prior Ubuntu versions". The following examples and the to be attached {s,l}traces files are produced with thunderbird from this debug enabled packages. There is *no* crash report in /var/crash.
This is the contents of mozilla-thunderbird_1.5.0.10-0ubuntu0.6.06_i386.changes as produced with aforementioned procedure:

Here is how I produced the attached strace and ltrace outputs with the above mentioned debug enabled thunderbird:

I modified /usr/lib/mozilla-thunderbird/run-mozilla.sh in line 166 to start thunderbird as follows:
strace -o /home/grfz/mozilla-thunderbird-strace.root "$prog" ${1+"$@"}

I started thunderbird like this:

grfz at pingu:~$ sudo rm -rf /home/grfz/.mozilla-thunderbird/; sudo mozilla-thunderbird
DOUBLE-CLICK: 400 --> -1 THRESHOLD: 8 --> -1 DOUBLE-CLICK: 400 --> -1 THRESHOLD: 8 --> -1 grfz at pingu:~$

--> configuration wizard --> 3 pane window --> no crash; find attached
mozilla-thunderbird-strace.root.

I modified /usr/lib/mozilla-thunderbird/run-mozilla.sh in line 166 to start thunderbird as follows:
strace -o /home/grfz/mozilla-thunderbird-strace.grfz "$prog" ${1+"$@"}

I started thunderbird like this:

grfz at pingu:~$ sudo rm -rf /home/grfz/.mozilla-thunderbird/; mozilla-thunderbird
DOUBLE-CLICK: 400 --> -1 THRESHOLD: 8 --> -1 DOUBLE-CLICK: 400 --> -1 THRESHOLD: 8 --> -1 grfz at pingu:~$

--> configuration wizard --> 3 pane window --> crash; find attached
mozilla-thunderbird-strace.grfz.

I modified /usr/lib/mozilla-thunderbird/run-mozilla.sh in line 166 to start thunderbird as follows:
ltrace -o /home/grfz/mozilla-thunderbird-ltrace.grfz "$prog" ${1+"$@"}

I started thunderbird like this:

grfz at pingu:~$ sudo rm -rf /home/grfz/.mozilla-thunderbird/; mozilla-
thunderbird

--> nothing happens find attached mozilla-thunderbird-ltrace.grfz.

 modified /usr/lib/mozilla-thunderbird/run-mozilla.sh in line 166 to start thunderbird as follows:
ltrace -o /home/grfz/mozilla-thunderbird-ltrace.root "$prog" ${1+"$@"}

-> nothing happens find attached mozilla-thunderbird-ltrace.root
