gst-launch-0.8 osssrc ! monoscope ! hermescolorspace ! xvimagesink

reproduces this bug.

however: gst-launch-0.8 osssrc ! monoscope ! ffmpegcolorspace ! xvimagesink

is fine.  Also

gst-launch-0.8 osssrc ! monoscope ! hermescolorspace ! ximagesink

is fine.

To note, I am using the binary nvidia driver...I havent been able to test it on
a non nvidia machine.

Some debug output, it manages to capsengo successfully twice...but the third
time (ie when pipeline has started, it fails).
