I'm using that version of keepassx on ubuntu 12.04.1 LTS myself quite extensively and do not experience these symptoms. Unfortunately, without a proper backtrace there is little that can be done about this problem.
See https://wiki.ubuntu.com/DebuggingProgramCrash for more information how to investigate this issue further. ** Changed in: keepassx (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/1050162 Title: keepassx crashes compiz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepassx/+bug/1050162/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
