It is pretty easy to replicate this bug by involving a Qt Window with
Qt::WindowTransparentForInput flag.
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
QDialog d1(&w, Qt::WindowTransparentForInput);
d1.show();
return a.exec();
}
Click d1 dialog, weston will crash due to NULL==shruf.
