This came up for the first time for me in Ubuntu 10.10 just now.
After the error, totem continued to play the video stream but not the audio stream.
I didn't wait long enough to see if it would eventually fail.
This comes after a rash of odd behavior from totem (gstreamer) in the last month. See bugs #644644, and #375224 / #246319 (possibly duplicates).
