Anupam: I don't see anything wrong from the media-hub.log, at least with this portion of the media stack. I'm thinking it may be an issue with pulseaudio but this bug will require deeper investigation to really know for sure. Anupam, which of the .ogg files listed in your media-hub.log do you currently have set for playing for SMS notifications?
Geoff: Can you please attach your media-hub.log file right after this occurs for you as well? I'd like to double check.
