crash when loading a lib on OS X

[Christoph Pingel]

Can anybody tell me what's going on here (or give me a pointer where 
to start looking):

I'm afraid that something's wrong with my system, but I had a hard 
time googling for getCPSProcessSerNum: it returned 0 results. Same at 
Apple's site...

What does CPS mean?

Thanks for any input,
best,
Christoph
