Public bug reported:

CID: 201404-14986 Dell Precision M2800

On this I+A (AMD/ATI Mars XTX [Radeon HD 8790M] [1002:6606]) system, the
GStreamer autovideosink plugin does not work well with the proprietary
fglrx driver (version 2:15.200-0ubuntu0.5)

Steps:
1. Install 14.04.3 + upgrade (3.19.0-30) + fglrx + Checkbox test suite
2. Run  "gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink"
3. Run "gst-launch-1.0 videotestsrc ! videoconvert ! ximagesink"

Expected result:
* A "Bar and static" video test screen will pop up.

Actual result:
* Only the command in step 3 will work, the command in step 2 does not, it will 
cause X to crash for sometimes, error log could be found:

Verified with the latest AMD driver(15.9, fglrx version:
15.201-0ubuntu1)[1], this issue does not exist with it.

As this issue will cause the camera display test and video test to crash
(whitelist test cases), I will mark this bug as a blocker.
