So, I took a closer look at the logs...
Seems like it's always a call to
0x93a57bf4 in _ZN7c4_View11AddPropertyERK11c4_Property
that's causing the 0x1 exception.
Does any of you know what this is about and what I should do?
Now, as a first try
I'll iron the disk and reinstall only the DVD - although I can't believe Apple sent me a broken OS.

Edit: A reinstall cleared things up, thanks God. I really didn't expect the thing to be BOA (buggy on arrival).
