That AFM file doesn't include a family name or a full name for the font
it describes. It seems that both are in fact optional attributes. I have
committed a change (on the trunk, and in the maintenance branch) that
should fix this, but since I don't have any AFM files like this, I can't
check that it works. Can you check out either the trunk or the
maintenance branch from Subversion, or apply the following patch and try
again?

[Matplotlib-users] Problem in afm.py with 0.98.3

[Berthold Höllmann]

I have a problem with every matplot version since 0.90.1. One of my
installed fonts causes afm.py to bail out. I am sure I reported this
problem before without reaction. After I installed python 1.6 and a
recent numpy 0.90.1 does not work anymore so I tried the latest again,
and get the afm error again:
