(g)mplayer: loop option problems with streaming media

Binary package hint: mplayer

When playing a media stream of finite length from the internet, if "loop=xx" (for example loop=0 to loop forever) is specified in mplayer's configuration file ~/.mplayer/config, gmplayer will go unresponsive after succesfully playing the media for the first time. Instead of restarting the media from the beginning when reaching the end, it becomes totally unresponsive and can only be closed using the 'kill' command (or ^C if on cli which is normally not the case).

Window decoration stays visible throughout, resizing the window and so on works but closing the program doesn't. With media files rather than streams no such problems happen, looping works as expected. When using 'mplayer' instead of 'gmplayer', looping does not work either but the program can be closed normally. Removing the loop option from the config file stops the closing problem from happening as well.

Kubuntu Feisty with mplayer 2:1.0~rc1-0ubuntu9
Command line output, just try a stream like this to reproduce:

$ gmplayer mms://a353.v227439.c22743.g.vm.akamaistream.net/7/353/22743/v0001/carlton1.download.akamai.com/12621/news/d5b3e13fbc0120eaa61628724061421a.wmv
