Changing the state of a pipeline with a sink with a preroll queue length
greater than 0 can lockup. I have attached a modified version of the stress.c
testcase that demonstrates the problem.

I found a possible fix for the problem - add code after the FIXME in
gst_base_sink_queue_object_unlocked (around line 1740 current CVS) to check the
return value of gst_base_sink_render_object and cleanup and return if it's not
equal to GST_FLOW_OK.
