Hm, freetype-2.1.4 refused to load the font entirely...

And freetype-2.1.10 crashes on some of the glyphs.

Whatever it is, it's clearly a freetype problem. It's interesting that
the version I use (freetype 2.1.9) doesn't have this problem.

Anyway, let's extract the font that causes this behaviour.

Could you please, in SWFOutputDev.cc (around line 2130), remove
the code

       if(fileName && del)
        unlinkfont(fileName);

? 
After this, run the conversion again, with the -v switch. 
One of the last log messages should read:

VERBOSE updateFont(...) -> /tmp/xxxxxxxxxxxxxxxx (max size: ...)

The file "/tmp/xxxxxxxxxxxxxxxx" is the broken font- could you post it
here? I'll then forward it to the freetype maintainers.

Thanks,

Matthias
