The packages I'm using are from the gstreamer ubuntu ppa.

While trying a simple gst-launch line:
gst-launch-0.10 gnlfilesource name="s1" location="/media/ASC.wmv" start=0 duration=5000000000 media-start=0 media-duration=5000000000 ! autovideosink

I got the following on the shell:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Caught SIGSEGV accessing address (nil)
Spinning.  Please run 'gdb gst-launch 11536' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

I attached to the gdb session, traceback bellow:
