jackd crashed with SIGSEGV in pthread_join()

[NoBugs!]

I haven't been able to start jack-server, which is required for some audio programs.
Is it possible to run in 9.10? Does it require replacing kernel with realtime kernel?

I awsn't able to reproduce this, and have used jackd fairly extensively in Ubuntu 9.10. There is no need for a realtime kernel. Can you still reproduce it? How about with `jackd -d alsa`? I usually start JACK with qjackctl, but I'm not entirely sure what that ends up producing as a command line.

I believe qjackctl writes it's jack command line to ~/.jackdrc
