I fetched the

        http://www.ozemail.com.au/~philcam/foxjump.zip

distribution with the Foxjump font, and tried several TTF tools on the
font:

        ttf2bdf
        ttf2pt1
        ttfdump
        ttfps
        ttftot42

The one anomaly was in this run:

        % ttfps FOXJUMP.TTF foxjump.pfa
        Inconsistency between `maxp' and `nglyphs' tables!

I then tried gs-7.03 to display the font:

        % cat Fontmap
        /Foxjump                (FOXJUMP.TTF) ;

        % gs prfont.ps

Perhaps these are also clues about what might be wrong.

Unfortunately, I don't have any tools that can convert from Type 1 (or
42) to TrueType; otherwise, I'd try a round-trip conversion.

I appear to have a local installation problem with the ttdump/ttundump
pair:

        % ttdump FOXJUMP.TTF
        Traceback (most recent call last):
          File "/usr/local/share/lib/FontTools/ttDump.py", line 31, in ?
            from fontTools import ttLib
        ImportError: No module named fontTools

This would have given a TTF -> XML -> TTF round-trip test.
