I suspect an explicit conversion to str may be required on your
configuration/platform. (I think you mentioned you were using Windows).
Can you change line 592 of mathtext.py to read:
font = FT2Font(str(basename))
and let me know if that fixes your problem? If so, I'll commit this to SVN.
Note that you may also have problems if there are any non-ascii
characters (with accents etc.) anywhere in the path to mpl's fonts. In
general mpl doesn't really handle Unicode paths correctly wherever C/C++
code is involved. Hopefully that can be resolved in a future version.
Cheers,
Mike
