gstreamer1.0, gst-omx, gst0.10 vs gst1.0

Here is a better pipeline that produces and describes the underlying problem:
(BTW, I'm trying to port our gst-omx components from 0.10 to 1.0-1.6.1, one
of which is the omxbufferalloc)
GST_DEBUG="*:3,omx*:9" gst-launch-1.0 -v videotestsrc !
'video/x-raw,format=(string)NV12,width=640,height=480,framerate=(fraction)30/1'
! omxbufferalloc num-buffers=5 ! queue ! fakesink
The above pipeline works fine without the queue (curious, only one frame is
queued during preroll), with the queue omxbufferalloc (which uses
omxbufferpool) we have a preroll problem shown in the following log. Please
see the "no more buffer" warning - gst_atomic_queue_pop() attempt to pop an
already empty buffer.
Which produces the logfile:
