I'm actually not experiencing this problem anymore. The only thing I can think of that I changed was the mouse focus settings, from "click to focus" to "focus under mouse".
Just now I've noticed that by changing it back to "click to focus" I am able to reproduce the crash. Hopefully this information helps fix the bug. -- closing a window causes kwin to sigsegv https://launchpad.net/bugs/57782 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
