apport information ** Tags added: apport-collected running-unity
** Description changed: I have a Dell mini 9 with a usb bluetooth adapter and a bluetooth headset. For the last while (possibly since the 3.8 kernel has been in raring) I can pair the headset, but within a minute bluetooth stops working and a black screen with white text flashes up briefly. Hereafter the sound indicator --> sound settings no longer shows any audio devices. /var/log/kern.log for this session is attached. Please let me know if you need any additional info.
