OK, fixed.

Thanks, I've added a note in INSTALL.txt

Actually the potrace "bug" is a non-bug; potrace crashes on empty
characters. What you see is a bug in mftrace .26. Upgrade to .27, and
you should be fine.  (using potrace is about 3 times faster than autotrace).

Thanks for your comments and patches, enjoy LilyPond.
