> #30 QApplication::~QApplication Interesting, the application is already in its destructor, still it tries to write data to the clipboard.
The QApplication destructor does: // flush clipboard contents if (qt_clipboard) { QEvent event(QEvent::Clipboard); QApplication::sendEvent(qt_clipboard, &event); } I don't know how I can reproduce that crash
As I found no way to reproduce it and kolourpaint is already using Qt5, let's close this one.
