I posted this to the Jitsi users mailing list on Thursday last and have received no replies. Does anyone here have any idea of what is causing this and how to fix it?

One other bit of information. When I first installed Jitsi it initially worked for a non-privileged user as I ran it from the gnome menu of my login account. However, at some point it seemed get 'confused' and hung. Since then I have been unable to get it to run as a non-privileged user. I have removed and reinstalled it. I have also rebooted the host. Nothing changes its current behaviour.

I installed jitsi-2.2 on a CentOS-6.4 x86_64 host. When I run it as a non-privileged user then I see this error:

$ jitsi ALSA lib pcm.c:2209:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2209:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2209:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm_dmix.c:957:(snd_pcm_dmix_open) The dmix plugin supports only playback stream

GThread-ERROR **: GThread system may only be initialized once. aborting... Aborted

and it dies.

If instead I run it as a privileged user then I see this:

And it works. What is going on and how do I fix it?
