[LAU] What is wrong with jackdbus?

[Phil CM]

Dear LAU

Whenever I'm starting to get xruns, I do a quick ps aux|grep jack and 
sure enough, in place of the usual

(...) /usr/bin/jackd -dalsa -dhw:XStation,0 -r48000 -p512 -n3 -Xseq

I get a nasty

(...) /usr/bin/jackdbus auto

I' suspecting pulseaudio to launch it (I use 3.13.0-36-lowlatency 
#63-Ubuntu SMP PREEMPT) so I edited

/etc/pulse/default.pa

To comment out those lines

### Automatically connect sink and source if JACK server is present
# .ifexists module-jackdbus-detect.so
# .nofail
# load-module module-jackdbus-detect channels=2
# .fail
# .endif

But nope, at some point, jackdbus rears its ugly head.
Then I have to reboot :[ because just killing -9 it prevents the jack 
server to start anew.

Questions

- What is wrong with jackdbus ?
- How can I prevent it from starting ?

Thanks
