[ardour-users] segfault starting ardour as non-root

[Orm Finnendahl]

Hi,

ardour segfaults when started by a non-root user. Starting jackd and
ardour as root works fine. Here is what happens: jack is started by
the user with

jackstart -R -d alsa -d hw:0 -r 44100 -n 2 -p 1024

It starts up o.k. When starting ardour and creating a new session,
ardour segfaults. Below is the terminal output. It seems there are
some permission problems.

Thanks for any hints,
Orm
