I didn't want to do a recursive call as I could not forsee if there is a 
way to get a dead loop. So I did it the hard way :)

If you're a beginner, the best way is to do it like you did. Post the 
problem here and some of the NutO/S guys will catch up. You can add 
DIFFs to your posts or someone will ask you for your modifications and 
integrate them. After a while there are options, that you can get write 
access to the repository.

So don't hasitate to write any bugreports and / or solutions. You're not 
alone :)

Best regards,
Ulrich
