Public bug reported: Using rtm image 184 on krillin
I was testing recording videos with camera-app and noticed that at some point during the recording process that pulseaudio was using 40% CPU and that did not ever get smaller. Then upon closing the camera-app media- hub-server and camera-app crashes. The following is the stacktrace which looks like pulseaudio crashed. Steps to reproduce: - open camera-app and record a bunch of videos using both front and back cameras - run top -d1 during this and you'll see pulseaudio using a lot of cpu - move camera-app to the background and try to swipe it away and you'll see the crash apport-retrace --gdb _usr_bin_media-hub-server.32011.crash GNU gdb (Ubuntu 7.8-0ubuntu1) 7.8 Copyright (C) 2014 Free Software Foundation, Inc.
