Sadly, after three (or six+) years, it is clear that these bugs will
not be fixed, and this warning message is not useful, since no one has
stepped up to fix them..

btw, you might want to create a bug w/ the information you tracked down
to hopefully help the person that decides to finally fix them, though
I doubt they will ever be fixed as people apparently don't see bad
behavior...

Unless someone fixes the bugs in the next few days, I will commit the
following patch:
