What exactly crashed — gnome-session or compiz? If it is compiz, I would like to recommend you to install these ddebs:
http://ddebs.ubuntu.com/pool/main/c/compiz/compiz-core-dbgsym_0.9.11+14.04.20140409-0ubuntu1_amd64.ddeb http://ddebs.ubuntu.com/pool/main/c/compiz/compiz-gnome-dbgsym_0.9.11+14.04.20140409-0ubuntu1_amd64.ddeb http://ddebs.ubuntu.com/pool/main/c/compiz/compiz-plugins-default-dbgsym_0.9.11+14.04.20140409-0ubuntu1_amd64.ddeb … then run compiz in gdb with "--replace" flag, trigger the crash and paste the stacktrace here. See https://wiki.ubuntu.com/DebuggingProgramCrash for details. Or, alternatively, configure Apport to submit crashes to Launchpad (see answer in http://askubuntu.com/questions/150476/ for the instruction) and submit the bug using Apport. ** Changed in: gnome-panel (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1306518 Title: gnome crashes when trying to switch to another workspace To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/1306518/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
