[ubuntu-mono] [Bug 1286559] [NEW] GStreamer crash (likely to happen when there are many inaccessible tracks?)

Public bug reported:

I think this bug doesn't happen with upstream banshee 2.6.2 (because
this one uses gstreamer0.10), but with downstream banshee 2.6.2 (which
has been updated/forked to use gstreamer 1.0). The crash log is the
following:

(Banshee:2250): GStreamer-CRITICAL **: 
Trying to dispose element playbin, but it is in PLAYING instead of the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element.
