Max,

thanks for taking the effort.

Yes there is potential but I don‘t see it. I take a fresh 6.1 image and load my 
project into. I‘m not sure but I think zinc 2.9.2 is loaded rather early in 
that process. So I wonder why it does not go wrong in the first phase. And also 
not if I load the test group within the first phase. 
It must be either the second Metacello invocation or the stopping, copying and 
starting of the image.
I try to isolate this case more and provide a script that goes wrong on my 
machine. But it will take some time because I needed to stop trying to solve 
this as I wasted nearly two days on that already.
