There is a (probable) fix for this in SVN r4179. I can't get to a Mac
to test right now -- can you please confirm that fixes your problem?
You may need to remove ~/.matplotlibrc/fontManager.cache (just once) in
case the earlier bug has messed up the cache.

Perhaps you have a lot of fonts on your system. I see your point about
the warning message, but sometimes when the user is presented with too
