Can't reproduce that any longer, however I get something possibly
related/similar when seeking (just starting playback, then hitting the
arrow-right key), namely:

(lt-totem:7428): GStreamer-CRITICAL **: gst_mini_object_unref: assertion
`mini_object->refcount > 0' failed

So refcount bug somewhere, maybe in the video decoder ?

Program received signal SIGTRAP, Trace/breakpoint trap.
