Well, glad you found the problem.
Also, doh for deriving the compatibility condition -- that was too simply for
me no
Issue resolved. I used the wrong sparsity pattern. That was just a typo in
the code. Sorry for having bothered you with this but anyway:
Many thanks,

Hi all,
I am encountered a weird thing (bug?) and I am having trouble to understand
it. Maybe someone has an idea:
I am trying to solve a simple elliptic problem (imagine some sort of a
simple Laplace problem for now) with pure Neumann BCs, say -\Delta u = f,
n\grad u = g. Now theory tells me
