Ha! Thank you very much, this was exactly the problem!

Our startup-scripts indeed seem to be abount two years old. I remember 
seeing a warning about old scripts once, but haven't seen them in a 
while and thought one of my colleagues fixed it.

If I may ask a following question.... how to rebuild the scripts? >_< I 
can't reproduce the old warning and either I'm too stupid to use Google 
or the howto is hidden somewhere in subspace...

Thanks and regards,
