I'm running Gutsy too and had this problem. In my case it happened when I restarted the x-server. Compiz doesn't work on my computer.
I've attached the crash report. ** Attachment added: "crash report" http://launchpadlibrarian.net/8753524/compiz-real.crash -- compiz.real crashed with SIGSEGV https://bugs.launchpad.net/bugs/122313 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
