[Bug 1176062] Re: System crashes when starting Firefox and/or Thunderbird

[Greg Supina]

Reply to request for more info:

The only changes to the system, since recent updates, is that the kernel
is now 3.8.0-22 generic.

By the way, the file manager is Thunar 1.6.2.

As mentioned above, the crash is not always reproducible and seems to
occur on an inconsistent basis. However, I can usually cause the
operating system to crash by first running either Firefox or
Thunderbird, then starting the other one of these two applications after
the first one has run. Therefore, the system crash is mostly related to
Firefox and Thunderbird, but the system sometimes crashes even when I
have not opened either Firefox or Thunderbird at all during the whole
session.

I caused the operating system to crash when starting up Firefox (after
previously starting up Thunderbird). Then I cold-booted the system and
the following was all that the dbg.txt file said:

Likewise, I caused the operating system to crash when I started up
Thunderbird (after previously starting up Firefox). Then I cold-booted
the system and the following was all that the dbg.text report said:

I hope this helps.

Thanks for looking at this problem.
