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.
