your blender settings are stored in a 2.62 (according to your output from above)
right, blender version 2.62
EDIT: ok, it is either a problem with the blender version or a linux depending problem. I retried on Win7 with blender version 2.67b and it works.
Anyway, on weekends I usually have only my Laptop available, where Linux is running, so I would be happy if I could bring it running there.
(sorry for my fatal english, just ask if my words are unclear!)
EDIT 2: Blender version 2.62 on Win 7 also generate the same error. So thats it. The next step is to try a different version on Linux.
If that is ok I will edit the Wikipage, maybe other people run into similar problems....
