Bug 333709

The desktop application crashes upon a incoming phone call.
I have the mute speakers when there is a phone call setting enabled, but instead of muting it crashes. I am using pulseaudio and phonon-gstreamer for the backend.

This is 100% reproduceable.

Reproducible: Always

Steps to Reproduce:
1. Receive Phone Call
Actual Results:  
KDE-Connect crashes.

Expected Results:  
KDE-Connect mutes speakers.

Here is the backtrace (although I don't now if it will be very useful):

Application: kdeconnect (kdeconnectd), signal: Aborted

If you need me to install some debugger or something I'm completely willing to help. Thanks for making this awesome program.
