The stacktrace is from a considerably older version of unity, nevertheless, the crash seems to happen in the construction of the CompizMinimizedWindowHandler object with a NULL pointer for the CompWindow * argument and
for (unsigned int &w : transients) { CompWindow *win = screen->findWindow (w); if (win) { Window::get (win)->mMinimizeHandler = MinimizedWindowHandler::Ptr (new CompizMinimizedWindowHandler (win)); Window::get (win)->mMinimizeHandler->minimize (); } } That is now protected by a NULL check. Since no duplicates have been registered on this crash, I will close the bug for now as fixed. ** Changed in: unity Status: Confirmed => Fix Committed ** Changed in: unity (Ubuntu) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/844813 Title: compiz crashed with SIGSEGV in CompWindow::id() To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/844813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
