[Matplotlib-users] TrueType font is missing table

[Neal B. <ndb...@gm...>]

Using mpl 1.4.3 on Fedora 22, I'm trying to use stix font (so I can render 
the unicode lambda label on the x-axis).  I have every fedora package 
related to 'stix', I think. It displays ok in qtagg4, but if I try to save 
to pdf if fails with
