Firefox always crashes on startup

[Benjamin Redelings]

This bug occurs on AMD64 gutsy with firefox version 2.0.0.5+2-0ubuntu2.

To reproduce:

1. Run firefox (from the command line, or not)

I think that this is AMD64-specific, based on another report that I saw.

You will see it open a window, draw the favico icon for a local html page, and then crash. If you run it from the command line, you will see it say segmentation fault.

When I enable core dumps and did this, it gave me a gdb session, and the following backtrace. I noticed the function ubuntulooks_draw_progressbar_trough and removed the package "gtk2-engines-ubuntulooks". Firefox now runs without crashing.

I don't know if this is a bug in ubuntulooks or in firefox, cairo, or libgtk2, though. Perhaps a bad interaction between ubuntulooks and cairo?

Thank you for the report, but this is not a launchpad bug, re-assigning to Ubuntu.
We're interested in why you accidentally recorded this bug as occurring in launchpad instead of Ubuntu. If you can explain what happened, please let us know in bug 88818.

[Alexander Sack (asac)]

try to change your gnome theme please.

[Benjamin Redelings (benjamin-redelings)]

I reinstalled the ubuntu-desktop and the stuff that it depends on.

Now, if I use the 'human' theme, then I have the same problems as before. That is, firefox always crashes on startup.

However, if I use the clearlooks theme, then firefox starts fine. Interestingly, if firefox is already running, switching to the human theme does not result in a seg-fault. This only happens under the human theme on startup.

Your retrace shows that it is the same crash in #123646
