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
