These other fonts behave properly:

Note: In all cases, the fonts seem to display OK in the font menu and there have been no reports of other "abnormal" activity. However, the suitcases, once installed cannot be dragged out of the 'blessed' Font folder. If you drag the entire folder to the desktop and restart, you can trash them (but you still can't open them).
