Re: [Matplotlib-users] PDF Backend problem still unresolved
Thanks for the reply, Jouni. I am running Python 2.3 on Windows XP, latest version of MPL. I'll see if I can reproduce the problem using standard examples.

Re: [Matplotlib-users] PDF backend problem
Jouni,
Are you certain the version you sent me is correct? It didn't make any
difference - I get the same error messages.

Subject: Re: [Matplotlib-users] PDF backend problem
I fixed another filehandle leak in the pdf backend, so here's
a more complete patch. There are also several cases of
file(...) being passed to pickle.dump or pickle.load in
font_manager.py. I was going to take care of these by writing
some utility functions, but I started wondering why the
import of cPickle or pickle is done only within methods of
FontManager and not at the top level. Are there some
platforms where neither is available, or what is the rationale?
