That seems like a good guess to me. Looking at the root.log for your build,
the only font package installed is dejavu-sans-fonts. That font package
only includes true type fonts on rawhide and this matplotlib code is looking
for afm fonts. One fix/workaround may be to include a BuildRequires/Requires
for a font that ships an afm font file.
Looking at the F17 version of matplotlib, the default afm font is being set
to None there -- so a better fix (but requiring fixing in matplotlib) might
be to patch it like this:
