I don't think these problems are related.  One is a cache of math 
expression images, the other is a cache of fonts.

I am unable to reproduce this on Matplotlib 0.98.5.3 on Linux (don't 
have a Windows box handy).  Can you run the attached script (which is 
just a modification of mathtext_wx.py to generate 60 different math 
expressions, and let me know if that crashes for you?  If not, we need 
to track down the difference between what this script does and what 
yours does that causes the crash.  Can you share a minimal script that 
reproduces the bug?  It would also be useful to see a traceback (you may 
need to run your script from the commandline in Windows rather than 
double-clicking, in order to get the full traceback output).

Thanks,
Mike
