TTF NullPointerException

I've got a truetype font I'm trying to convert using the ttf2svg converter and I get the following error:
java.lang.NullPointerException
        at org.apache.batik.svggen.font.table.GlyfCompositeDescript.<init>(Unknown Source)
        at org.apache.batik.svggen.font.table.GlyfTable.init(Unknown Source)
        at org.apache.batik.svggen.font.Font.read(Unknown Source)
        at org.apache.batik.svggen.font.Font.create(Unknown Source)
        at org.apache.batik.svggen.font.SVGFont.main(Unknown Source)
        at org.apache.batik.apps.ttf2svg.Main.main(Unknown Source)
null
usage: java org.apache.batik.svggen.font.SVGFont <ttf-path> [-l <range-begin>] [-h <range-end>] [-ascii] [-id <id>] [-o <output-path>] [-testcard]

I'm using the following command to convert it (and I copied one of the wingding ttf fonts and converted it and it worked just fine) - it's just like the example in the docs:

java -jar batik-ttf2svg.jar techno.ttf -l 48 -h 57 -id MySVGFont -o mySVGFont.svg -testcard

Doesn't work for the techno font, but does for webdings.  Any idea why one ttf would cause a NPE and the other wouldnt?

Thanks,

- Brent

Hi Brent
 
If you could tell me how to get hold of the techno font, I'll attempt to
reproduce the problem.  It would appear to be a problem with a composite
glyph, perhaps referencing a bad simple glyph, but I will need to debug
with the problem font.
 
Regards,
 
David Schweinsberg

Sorry for the delay.  If anyone is interested in testing this out I can send
the TTF file as an attachment directly.  I just didn't want to send a 56KB
attachment to everyone on this mailing list.

Thanks,

Brendt,

Could you give us a little more information about the font (techno) 
you are using (e.g., where could we get it to reproduce the problem)?
Thanks!
Vincent.
