Uhm, right, overlooked that one. 
But the problem still persists, what I see here is:
KeyError: -1212033192L
Traceback (most recent call last):
  File "simpletreemodel.py", line 88, in data
    item = self.itemdict[index.internalId()]
KeyError: -1212033192L
Traceback (most recent call last):
  File "simpletreemodel.py", line 88, in data
    item = self.itemdict[index.internalId()]
KeyError: -1212033096L

And that is with the latest snapshot. I have absolutely no idea how that
can happen and so far it seems I'm the only one seeing this.
