Script which segfaults when the pipeline is set to NULL

The attached script segfaults when it should not. The role of PAUSING the "gltestsrc ! gleffects ! fakesink" pipeline in the script is to detect whether the opengl effects can be used.

I'm using an nvidia card. Thibault is using a different video card and cannot reproduce.
