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?
Thanks,
- Ivan
