Comment 5 for bug 163380

I also got the same message but in a different setting. I was trying the YouTube plugin in Totem and picked a random video (http://www.youtube.com/v/EqBD_rmIU4A). The error occurred when Totem got to that item in the playlist. I tried gst-launch and got pretty much the same as above:

burt@ciabata:~$ gst-launch-0.10 playbin uri=http://www.youtube.com/v/EqBD_rmIU4A
