Besides repairing the permissions from the recovery, I also tried to fix them with Rom Manager, too.
Unfortunately, it did not fix the problem.
Update: it seems so much strange that a kernel could cause such problems. I read somewhere that the "problem loading widget" message usually appears when the widget is not able to load some resources. It smells like a permissions problem, of course.
Update 2: I also am no more able to fix permissions through rom manager, it gives me a generic error
