Zipped gstreamer log, 'gl*' catergor heavily

I have setup the following playback pipeline:

"playbin video-sink="glupload ! glcolorconvert ! appsink name=appSink0
caps=video/x-raw(memory:GLMemory),format=RGBA,texture-target=2D""

... in order to catch video frames in openGL format and pass them along to be
rendered by a third parts (ultimately a Unity app)

I was seeing slow down after ~7 seconds, then a crash after maybe 15 seconds.

Here is the trace that Unity spits out:

Thinking it might be my code, I tested playback with the pipeline using the
following gst-launch command:

gst-launch-1.0 playbin
uri=http://rdmedia.bbc.co.uk/dash/ondemand/bbb/2/client_manifest-separate_init.mpd
video-sink="glupload ! glcolorconvert ! appsink name=appSink0
caps=video/x-raw(memory:GLMemory),format=RGBA,texture-target=2D"

After approximately 15 seconds gst-launch crashes.

In addition, I ran the same gst-launch command with the debug option
'--gst-debug=3,gl*:9'.  The log for this is attached - gst.txt within gst.zip.

Last bit of additional info.  Thinking it might be linked to playing an
adaptive (DASH) stream, I tried a 'local' h.264 (big buck bunny) mp4 video
file...with the same resulting crash.
