From time to time the gst-rtsp-server segfaults when stressed with PAUSE/PLAY requests.

I am using Ubuntu 11.04 with GStreamer PPA, gst-rtsp-server is from git.

At the server side i run ./test-launch "( videotestsrc ! video/x-raw-yuv, width=640, height=480, framerate=50/1 ! x264enc ! rtph264pay name=pay0 pt=96 )"

Client used to reproduce the bug.
