----------
This is no (known) bug of UGGrid, rather a shortcoming of the PDELab backend. The preconditioner adds matrix entries for the border vertices. Stuff simply is wrong, if other border degrees of freedom come into play. 

This has been discussed also on the PDELab mailing list, http://lists.dune-project.org/pipermail/dune-pdelab/2012-January/000285.html. 

A PhD student in another group here in Stuttgart wanted to work on this. I can send you his name.
