The original email (not sure if you saw it, sorry) said that the fonts
were converted from OTF to TrueType using FontForge.

In the earlier bug report, someone was using mftrace to convert
MetaFonts to TrueType.  According to the mftrace web page, it uses
FontForge to generate TTF output.

TrueType fonts can be embedded directly in PDF files, so my assumption
was that the TTF error was being introduced by FontForge.

But it looks like both cases were also using fop as the last stage (to
actually generate the PDF file), so the bug may actually have been in
fop.

Jeremias - can you look at this?  I know you found one bug in fop
yesterday (regarding the numTables problem).  I'm wondering if the other
bug (invalid table directory entry - all zeros other than the tag) is
also in fop.
