The same object is indexed twice but with different paths.
I managed to solve to problem by making sure the object is accessed 
always in the same way.

Before, I used acquisition from outside the
portal to get access to the object before I called the edit method.
This seems to confuse the catalog.

Now I use path traversal from root of the portal and the problem is
gone. I still don't know what exactly the problem is though. :(

If I have time I'll try to device a small example to illustrate the 
behaviour.
