A number of other apps from svn have jack svn as a dependency. This
means, for instance, that if I want mute groups in hydrogen, which is
something I need for what I am trying to do, I have no option but jack svn.

I tried to use jackdmp instead, but I couldn't get qjackctl to recognise
it. I considered rolling back to a stable version of jack, but as I had
had trouble with earlier versions as well, I wasn't sure I would be much
better off. I might yet reconsider, but then again it sounds like people
are working hard at putting things right so it might be better simply to
be patient a while longer.

But yes, I shall certainly try to get some core dumps next time I do
some tootling.

Many thanks
Robert
