a) How did you close the window? (titlebar button, popup, alt+f4, ...) b) which window decoration do you use? c) does it happen with other decorations as well? We need the information in order to investigate the crash. Crash with similar backtrace just happened to me (Ubuntu 12.10, Qt 4.8.2, KDE Platform 4.9.0, standard oxygen decoration). No memories on what triggered it though :-| Do you still have the backtrace? (If so, please post it) Also most important question -if you can recall that- is how you closed the window. (If you clicked the close button that's it there's no special click closing but other close operations and the window could have closed itself as well) Sorry, no backtrace. The call stack looked like the above one, except DrKonqi shortened the other threads, and gcc optimized almost all arguments away. I was serious about "no memories", I cannot even remember whether I was closing a window at all - sleep deprivation… *** Bug 306525 has been marked as a duplicate of this bug. *** Dupe connects this to bug #288454 and from there pot. to bug #216879 Anyone reproducing this volunteers to valgrind kwin?

I attempted to close a Mathematica window by clicking on the close button in the titlebar. The style in use is oxygen.
