I've just tested it with the latest petsc[4py]/slepc[4py] versions from the
maint branches. A modified petsc C example as well as a modified slepc4py
example now lead to the expected behavior. For my last tests, which I did
in June, I used petsc/slepc 3.5 - maybe this was the reason why it didn't
work.
