[X11DRV] Fix crash on bad fonts...

[Lionel Ulmer]

> Why not print a user message here that such and such font might be broken?

Because I prefer having Wine working without any user intervention than
having to hold hands to people not understanding why they should remove this
font (and not knowing how to find it or how to delete it).

Feel free though to add the message and do the support on #WineHQ later on
(not that we see you much there lately :-) ).
