It started to happen to me too, after some library upgrade, I guess.

(debug) 22:44:12 void
PhoneCall::setState(EnumPhoneCallState::PhoneCallState): call state
changed callId=1 state=PhoneCallStateTalking
(info) 22:44:12 virtual bool PhApiWrapper::isCallEncrypted(int): Call
with callId 1 has encryption mode 0
(debug) 22:44:13 void QtPhoneCall::rejectCall(): phone call hangup

Program received signal SIGSEGV, Segmentation fault.

The backtrace is not exactly the same, but I think the cause is the
same, as it is happening at the same time. I find it particularly
difficult to debug, as I do not know much about programming with alsa.
