 I keep having a strange problem with Totem (using the Gstreamer backend).
 Every so often when I watch a movie, the video slows down to only a few
 frames per second, but audio is fine. This can happen spontaneously, but
 is easiest reproduced by pausing the movie for a long period (several
 minutes) and resuming playback.

 Restarting Totem doesn't help, I still get slow video and normal audio,
 but restarting pulseaudio gets everything back to normal.

 When this happens, pulseaudio starts using a lot more CPU than normal, it
 goes from 2-3% up to 18-19%. Usually this is where it shuts down
 automatically, so I'm now using "no-cpu-limit = yes".

 I'm using PulseAudio 0.9.13 on Debian sid/unstable, kernel 2.6.27. The
 built-in sound card is identified as 00:1b.0 Audio device: Intel
 Corporation 82801JI (ICH10 Family) HD Audio Controller.

 I'm attaching backtraces from both totem and pulseaudio when this happens.

 A very similar problem is discussed in this Ubuntu bug report;
 https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/221488

 It's also similar to ticket 240, but I haven't used suspend before this
 happens.
