Hi-
I've got two Intel OSX machines running matplotlib.
I recently upgraded one of them to the latest MPL svn. On one machine,
I had some pytz-related problems which I resolved, and I was able to use
it more or less fine. However, when the very first time I started it,
there was a huge pause which I eventually realized had something to do
with the font cache, but it seems OK since then (but perhaps there
should be a warning message when the cache is being built?)
On the other machine, however, I got the traceback below, which I
eventually traced to the call OSXInstalledFonts() in findSystemFonts().
Unfortunately, OSXInstalledFonts() is really
OSXInstalledFonts(directory=None, fontext=None)
which then calls
fontext = get_fontext_synonyms(fontext)
which fails with fontext=None.
I was actually able to fix this by copying the .matplottlib directory
from the working machine, but it's still clearly a bug!
Yours,
Andrew

Actually, sorry, this *doesn't* fix the problem on machine number 2 (it
just lets ipython -pylab start without crashing, but actually calling,
e.g., plot(x,y) still fails for the same reason).

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
much information, they just train themselves to ignore all of it...

OK, the fix in the latest SVN does seem to work.
