I was able to reproduce and fix the problen on windows. It occrs because
Embperl was not able to unload correctly. It's now fixed and commited to the
CVS. Hopefully Angus will create a new debian package soon, but I am not
quite sure when he gets up. If anybody wants to test inbetween, I can
provide a standard tar.gz file for Embperl with the fixes.
