I know you are going to ask me to try on the latest but that means having to upgrade to GNOME 3 and/or Unity (on Ubuntu) and neither of those are usable yet so I'd prefer to just stick with GNOME 2.32.1 that I currently have/use.

There's a GStreamer PPA with more recent versions of GStreamer. You can upgrade glib/gstreamer without upgrading the rest of your desktop.

Please try with an up-to-date version of GStreamer (current pre-releases or latest release, ie. 0.10.35.2 or 0.10.35 of core/base and 0.10.30 or 0.10.30.2 of -good).
Comment 2 Brian J. Murrell 2012-01-19 21:42:27 UTC 
While this problem didn't happen super frequently, it has not happened even once since I started using the PPA release so I think we can close this ticket.
Comment 3 Tim-Philipp Müller 2012-01-20 12:56:47 UTC 
Ok, thanks.
Comment 4 Vladimir Rutsky 2012-02-05 00:09:43 UTC 
After upgrading from Ubuntu 11.04 to 11.10 I experienced this bug with similar stack trace very often. 

In my case the problem was due to bug in fuser program [1]: fuser forked uncontrollably and exhaused all my threads resources (number of threads limited to 600 in /etc/security/limits.conf in my system), so any program that tried to create thread at the same time that fuser was running have been failing. 

Patching fuser program [2] helped.

P.S. I'm using GStreamer 0.10.35-1 from Ubuntu 11.10.
