Maybe the bindings don't expect gst_init() to change the argv that is
passed to it... and then later the CLR accesses invalid memory?

Best would be to report a bug about this at http://bugzilla.gnome.org
against GStreamer/gstreamer-sharp :)

As a workaround for now you could just set an environment variable
before calling Gst.Init() (GST_DEBUG for example), or just call
gst_debug_set_default_threshold(GST_LEVEL_DEBUG) for example. There's
probably a variant of that function in the bindings too.
