> #30 QApplication::~QApplication

Interesting, the application is already in its destructor, still it tries to write data to the clipboard.

Comment 2 Martin Koller 2014-05-03 17:03:46 UTC

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

Comment 3 Martin Koller 2016-11-12 14:53:07 UTC

As I found no way to reproduce it and kolourpaint is already using Qt5, let's close this one.
