After a bit of digging I found that the problem is caused by the line: KPX Y ydieresis -'0 in the font files jkplmsc8a.afm and jkpmsc8a.afm installed with the package texlive-fonts-extra. When afm.py parses this line it fails because it can't convert the last token "-'0" to float. I don't know much about AFM so I'm not sure what is the best way to fix this. Should I modify afm.py to handle this line (remove the single quote) or edit the afm files? And to whom should I send a bug report, matplotlib or texlive-fonts-extra?
