Yes, I know. The problem is that in libkpathsea4 there is a bug that 
is only triggered with loads of fonts (AFAIS). 

I cannot upgrade TL2007 packages for Debian now that 2009 is already in
unstable, but the patch would be attached.

I see two options:
- build your own kpathsea4 library and link it statically, but then
  apply the attached patch, otherwise it will break
- make sure that the header files in /usr/include/kpathsea/ are used
  and not the ones in the package (tetex3), and link dynamically 
  against libkpathsea5, in this case no patch needed.

One of the two will resolve the problem (I opt for the second, if that
is possible).

Best wishes

Norbert
