glcolorconvert fails to convert video buffer on OS X El Capitan 10.11.2.

My pipeline's video branch can be described by the following :

uridecodebin ! queue ! glupload ! glcolorconvert ! appsink

The uridecodebin linking with the rest of the elements happens inside the
pad-added callback of uridecodebin.

The pipeline will preroll and go to PLAYING state and I can even render the
first textures that arrive but then it throws complaining the the input memory
must be GstGLMemory.

Caps are set as video/x-raw(memory:GLMemory) on the appsink and glupload seems
to also transfer GLMemory to glvideoconvert so I am not sure where the issue
lies..

The same code works on GLX and EGL ( with 1.8.1 -- haven't tried 1.8.2 yet on
these platforms. )
