I have not yet investigated the problem thoroughly, but as far as I'm
aware it's caused by complicated outlines -- the font file contains
only 1 character, with about 1000 points in it.
If anyone wishes to examine the file in depth, I'd recommend using TTX
(http://www.letterror.com/code/ttx/ ) - it does font<->XML conversion
and makes it easy to see all the information in the file in human
readable format.
