Same crash for me but I didn't change any themes.

Crashed during system update. Probably a shared file.

Please, try to obtain a backtrace by following the instructions on https://wiki.ubuntu.com/DebuggingProgramCrash.

(install notably packages 'firefox-3.0-dbgsym' and 'gdb'. You will have a problem of dependency but select the first solution (which does not uninstall ubuntu-desktop)
and see here for backtrace https://wiki.ubuntu.com/Backtrace)

Set to incomplete until we have a backtrace or more info.

I've added the repositories listed in the first link but, as you say, I have a dependency problem and I'm not sure how to get round it - I don't understand when you say 'select the first option (which does not uninstall ubuntu-desktop)'. :-/

I ran sudo apt-get install firefox-3.0-dbgsym gdb and it says that gdb is at the latest level but that:

The following packages have unmet dependencies.
  firefox-3.0-dbgsym: Depends: firefox-3.0 (= 3.0~b5+nobinonly-0ubuntu3) but 3.0.3+build1+nobinonly-0ubuntu0.8.04.1 is to be installed
E: Broken packages

I have the newest version of firefox-3.0

Can you tell me what I need to do to resolve the dependency and I'll get the backtrace?

Thanks,

Laura

Indeed, there is a problem on Intrepid to install debug packages of firefox. They should update the debug packages in order to be installable. See: https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/259900
