This is caused by a bug in Ghostscript.  The bug is that if a Type 3
font invokes `fill' or `stroke' within any extra levels of gsave, the
character outline will be discarded, rather than appended to the path
being accumulated.

The fix is not a simple one, and is spread out over 4 different
files.  It will be in the next release.
