Comment 1 Myriam Schweingruber 2016-02-02 10:54:22 UTC 
The crash is in the phonon-backend. Is this crash reproducible?
Comment 2 Martin Nyhus 2016-02-06 14:42:00 UTC 
I haven't been able to reproduce it, and I haven't seen it since.
Comment 3 Myriam Schweingruber 2016-02-06 23:16:54 UTC 
Thank you for the feedback. Unfortunately there is very little we can do about this, as we need to be able to reproduce a bug to fix it. Please feel free to reopen this report if you can reproduce it and give the steps on how to do it.
