Thanks for reporting this.  I had seen that exception before but could 
not replicate it.  Stian is working on it now.

The exception, though annoying, should not affect the functionality of 
2.1 beta 1.

Have you set the dot location under Preferences -> Workbench ?  That 
might explain why you can't see a diagram.  Please let me know if that 
doesn't work.
