Hey Ralf

It has been sometime that I did anything with jack and I was also
surprised when this happened. The connection did not stay up; as soon
as a client connected (like mplayer) the connection stopped.

This looked something like a dbus event, but the jackd binary in
jack2, although coupled with jackdbus, should have no business with
dbus. It did not occur to me that it might be a kernel issue.
Installing standard jack solved the problem, but I had this in my TODO
(since it means jack2 is basically broken, but we have not received
any reports so far).

It would help if you could come on to IRC #jack or #archaudio so we
could troubleshoot this.
