 When I run jackd from the 64studio version of qjackctl, jackd crashes
 either straight after starting, or within 5-10 minutes, with the following
 error in the log:

 {{{
 09:07:45.867 Audio connection change.
 09:19:12.707 MIDI connection graph change.
 09:19:12.708 Shutdown notification.
 09:19:12.709 Client deactivated.
 09:19:12.710 JACK was stopped successfully.
 zombified - calling shutdown handler
 cannot send request type 7 to server
 cannot read result for request type 7 from server (Broken pipe)

 }}}

 This does not happen when I run jackd standalone, or using the debian
 stable version of qjackctl. It does happen even when qjackctl is the only
 jack application running. Also note that the crash happens straight after
 a midi connection graph change, which makes me think that it is a bug in
 the midi subsystem of qjackctl (64studio version). I am using an M-Audio
 firewire solo card, with the freebob / ffdao jack driver.

 jackd is started with the following parameters:

 jackd -v -R -P89 -t2000 -dfreebob -dhw:0 -r48000 -p256 -n3 -i0 -o0
