BUG/MEDIUM: config: do not propagate processes between stopped processes

Immo Goltz reported a case of segfault while parsing the config where
we try to propagate processes across stopped frontends (those with a
"disabled" statement). The fix is trivial. The workaround consists in
commenting out these frontends, although not always easy.

This fix must be backported to 1.5.
