Possible temporary workaround: I've had this problem quite a lot since upgrading while running matlab as others have commented. Once the error message pops up, answering yes/no/cancel all results in losing all window decorations.
However, if instead of answering the error message, if you merely minimize the error dialog, the window decorations continue functioning apparently indefinitely. I only have an N of one here, so YMMV, but until the patches come, it appears to work for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/727143 Title: unity-window-decorator crashes with SIGSEGV when closing Java windows -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
