[Matplotlib-users] mathtext and fonts under Windows 8

Hi, All,

I am encountering a thorny problem when trying to run matplotlib under Windows 8.  If I label an axis using a command like

ax.set_ylabel(r'time (s)', name='Arial'),

all is well.  But if  try to add mathtext to that, as in

ax.set_ylabel(r'time ($s$)', name='Arial'),

mathtext.py throws an error (a very long stream) ending in "RuntimeError: Face has no glyph names".  If I remove the "name='Arial'" above and let the program default to Bitstream Vera Sans, the mathtext works.


This problem does not occur under Windows 7 or XP; only under two different Windows 8 installations.  Any ideas what's going on?
