Try this:

 $ gst-launch-0.10 playbin2 uri=rtsp://66.111.34.191:601/broadcast/alnour.rm

Wait for audio to play, then hit Control-C. Result:

ERROR default gstrtspconnection.c:1479:parse_request_line: invalid method ]�f����IBU

That doesn't look good, and valgrind also complains about memory access (comparing buffers in caps though, so that may not be related). Tried to track this down, but lost motivation in the maze that is GstRTPConnection.
