What's even more surprising is that the behavior seems to differ
across applications. For example on the very same system I can
reproduce the kcolourpaint crash pointed by Martin, but I cannot
reproduce the crash in [1], which according to the stacktrace is also
happening because of a null mimeData pointer from the clipboard.
