----------
I'm getting the impression that the matrix classes used in the generic-fem stuff are somewhat broken.

Have a look at coeffmatrix.hh, lines 240-245 and 199-204.
The skip_ vector is allocated with size+1, but is only initialized till skip_[size-1]. The last entry is unitialized and might thus be removed. But if I change the allocated size to size, I obtain a valgrind error 
"Invalid read of size 4"
in Dune::SparseCoeffMatrix::mult (line 122)
