catching a system error

Using Tkinter and tkFont I'm trying to display all the different fonts
on my system. Mostly it works but some of the fonts bomb out. Perhaps
because the font is defective or doesn't have a character that I'm
trying to display. Anyway, even though I've got the code in a try/except
block the program crashes with an error like this:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  45 (X_OpenFont)
  Value in failed request:  0x2400094
  Serial number of failed request:  5573
  Current serial number in output stream:  5574

How can I catch this error either before (by inspecting the font) or
after so the program can continue?

debian linux, python 2.3.4
