It would be very useful if you can attach a backtrace of it. In order to do so, you can login in a virtual console and launch the following command: gdb /usr/bin/gnome-session -p pid_of_your_gnome-session
Once you reach gdb prompt, type the following instructions: handle SIGKILL nopass stop print handle SIGQUIT nopass stop print cont Now you can use your GNOME session normally and, when crash occours, you can switch to the virtual console and obtain a backtrace with the following instructions: backtrace info regs thread apply all backtrace Those informations will be very useful to triage this bug. -- Gnome 2.16 crashes after loading some apps https://launchpad.net/bugs/65971 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
