crash on incoming sms

I was just having a look before lunch, the backtrace says

Maybe not really unity8 related?

It took a long time, but I successfully reproduced this once.

In further support of @aacit http://pastebin.ubuntu.com/11231000/

In Notification.qml
If I check the availability of the audio hardware around the time of this bug, it is reported as busy. Perhaps media-hub crashes and then never releases the hardware

http://doc.qt.io/qt-5/qml-qtmultimedia-audio.html#availability-prop

Need to check if already fixed in vivid, sounds familiar
fwiw I only have a telephony-service-approver crash in addition to unity8

Has this been every fixed? I currently have this problem with my BQ E4.5 OTA-15.
When I receive any SMS, I press Power button, see the notification and then the phone crashes.
It keeps trying to restart Unity8 (ubuntu logo with dots), but it does not succeed.
I long press the power button to restart the phone.

@konrad this is a very old report that was not reproduced after a time. I saw several posts to the mailing list about this new problem, could you please open a new report and add logs there.
