over 200 font.cache files and growing.

[Sean Fraley <sfraley@rhiannonweb.com>]

I just installed sid and kde 3.1.1.  I noticed a weird flickering every time I 
displayed my home directory in konqueror.  On a hunch, I selected the show 
hidden files option and noticed that a ridiclulously large number of 
font.cache files werebeing created and deleted on an almost constant basis.  
Since the creation of files is a slightly expensive process, I'm pretty sure 
that this is having an effect on my performance.  Most of the files are empty 
(0 bytes).  Why is this happening and how do I stop it?
