mplayer segfaults on playing RTSP stream

[lars.g.kjellberg@…]

When playing the stream at URL: rtsp://streamer-01.dr.nordija.dk:80/dr1high, mplayer gives op with SIGSEGV.

VLC plays the stream just fine. It reports that the stream has one audio stream (mpga codec) and one video stream (h264 codec).

Debug information follows below:
