I have used the same Document>settings in all subdocuments,
but your proposal with an external file is much better and I will use it from 
now on. 
I guess it has to do with the aux file being used differently if I use the 
whole document (starting with the master docu) versus just a chapter sub-docu

continuing this I found out that the error was due to a reference. But it 
can't be the reference itself, since the same one is used at another place 
without giving troubles. There were two further references in front of it; 
moving it to the begin of the three citations in a row did not help. I put it 
in a note for the time being until I find a solution. I remember that this 
occurs apparently occassionaly in a koma-book-setting with two columns.

I appreciated your help and the one of others very much.
