Jack (the daemon, not the library) is not installed by default in Ubuntu 
11.10. Maybe you installed something else that pulled it in as a 
dependency.

But anyway, the server should not be started unless you run a program 
that requires JACK, which is the essence of the problem here.

It should work out of the box, with module-jackdbus-detect enabled as 
the default; but we're not there yet. Still bugs to fix last time I checked.

That looks like a crash/bug though, that might be worth investigating 
further.
