It looks I have the same. I was playing with gnome-sound-properties changing Audio Conferencing->Sound Capture combo and crush dump was generated. Now Sound Preferences hangs for a while if I touch this combo.
I may add more info if it's required. Crash dump attached: it looks like kind of infinitive recurrence to me...
