Comment 14 for bug 1398560

I was able to reproduce this issue by doing the following:

1. Open camera-app
2. I recorded a single video, then swiped to the camera-roll to preview it, then played it in mediaplayer-app by tapping on it in the camera-roll.
3. I did #2 again for another video.
4. Then I started recording several videos in a row without trying to view them after each recording. Once I recorded my 5th video, I noticed that the thumbnails were no longer appearing in the camera-roll. I also noticed that playback no longer worked if I tried to play any of these videos.
5. Once I removed ~/.config/pulse and rebooted, thumbnailing and playback of these videos all started working again.

So it seems that we are getting a corrupted pulse config from video recording.
