        <pre wrap="">Thanks, this is helpful, but it is spawning some new questions from me.

The error appears to occur while you are doing something in the system tree on 
the left hand side. A lot of different paths cause this code to run so I would 
like to narrow it down a litte. 

- Are you clicking the 'expand all' button on the tree when this happens?
- Are you clicking to expand some part of the tree, if so which part?
- Are you clicking from one element in the to another? If so from which part 
to which part?

I am trying to narrow down exactly what is causing this so I can reproduce and 
fix it here.

Thanks,
Alexander

ps.
In the meantime I will open a bugzilla on this so we can track it properly.
