I'm very sorry, but I forgot the exact error message. However, the
demo in /usr/share/fenics didn't contain that line at all and I simply
used the file there. I remember that the the calling function had
"amg" as argument per default later. That was the solution. No
wrapping call using has_krylov_solver_preconditioner anymore.

Thanks for the immediate reply,

Roland


PS: I'll have a look at it at the weekend and can recreate it maybe then.
