Sorry for a late reply. I couldn't figure out what's the problem a week 
ago and moved to a new flat in the meantime :). Now I returned to it and 
found the culprit,

Your code is correct. It is a bug in the rdf2go adapter implementation.

the removeAll() method from the RepositoryModel class deletes everything 
from all contexts, which is wrong. A model should only work on a SINGLE 
context. I'll try to pull appropriate strings to get this fixed asap.

Thanks for the report, and once again sorry for the delay.
