This may have nothing to do with the crash, however this is the sequence of events
Started Natty from hibernation (which usually works quite well) Had to power the system down and restart from sctatch. Sysyem came up fine, but failed when I started Firefox. Crash message followed and Firefox continued. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/554510 Title: plymouthd crashed with SIGSEGV in ply_list_get_first_node() -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
