[NTG-context] texexec doesn't finish

Hi. I am writing a short note in the hope that someone else ran into the same problem and can tell me what to do before I have to start thinking: I am using ConTeXt for a few weeks now without major problems. Today I felt like updating to the latest version (Aug 21?). Now when I try to generate even the simplest document (like 'texexec --pdf test.tex), texexec never finishes and spawns huge numbers of perl jobs. Any hint what I did wrong?
