Shows memory usage before opening a pipeline.

I have a working application.
In my application I always shutdown the pipeline and make a new pipeline for every new video source.

For performance issues I reworked the original pipeline:

	gst-launch-1.0  
		souphttpsrc location=<URL> is-live=true ! \
		image/jpeg,framerate=25/1 ! 
		jpegparse ! 
		omxmjpegdec ! 
		videoconvert ! 
		videoscale add-borders=true ! 
		video/x-raw,framerate=25/1,format=RGBx,width=800,height=480 ! 
		autovideosink

to:

	gst-launch-1.0 souphttpsrc location=<URL> is-live=true ! \
		image/jpeg,framerate=25/1 ! \
		jpegparse ! \
		omxmjpegdec ! \
		glupload ! \
		glcolorconvert ! \
		glcolorscale ! \
		"video/x-raw(memory:GLMemory),framerate=25/1,width=800,height=480" ! \
		videorate \
		glimagesink


CPU is decreased a lot but there is a major memory leak.
After 10-20 times shutting down the pipeline and creating a new pipeline the application crashed because of memory allocation problems.
I have replaced omxmjpegdec with jpegdec decoder and the problem is the same.
With the original pipeline the application has been running for days...
