Oh. Aha. mmh. right :) Thanks for the backtrace.

pthread_getschedparam(jack_client_thread_id (j_client),..

jack_client_thread_id() was always NULL because it was called before
jack_activate(). I suppose some systems don't like that, while others
simply ignore pthread_getschedparam(NULL,...). I did not dig into
pthread implementation just now.

I've pushed a fix (call jack_activate() before pthread_getschedparam())
which should resolve this issue.
