Hi Alan,

I'm not sure what is going on here, but I can tell you that the Verdana font is 
somehow being corrupted, specifically the sfnts data.  This font works fine for 
me with the simple_plot example.

Comparing the embedded fonts in the two .eps files, shows that the font in your 
file is corrupted.  There are two possibilities here: either your TrueType Font 
(TTF) file is corrupted, or your binascii.b2a_hex function in the Python library 
is producing corrupted output.  This function converts the TTF file to ASCII hex 
and is likely to be the culprit, since the length of some of the lines in sfnts 
array are incorrect.  They should be 72 characters in length unless they begin 
or end with a '<' or '>', resp..
