Nope, the bug is different (and in KMidi): KMidi creates a dedicated QWhatsThis
object for the main window instead of using the static functions. A dedicated
object for a certain widgets indicates, that help is available. In this case
this help for the main window is empty (the ugly square you are seeing).

That _is_ the background widget's help as specified by KMidi.

Anyway, I added a workaround in Qt. It now refuses to show empty squares even
if the program specifies that.
