Did some updates from Discover and after the reboot i got KDE Connect crash reports with phone and computer unable to see eachother. Did the pairing again and now i get crash reports everytime i try to pair them (and they still cant communicate anyway).

STEPS TO REPRODUCE
1. Pair computer and phone
2. Accept the request
3. Crash report window appears with this error: 
Executable: kdeconnectd PID: 11830 Signal: Segmentation fault (11)

OBSERVED RESULT
Sometimes it does connect but cant communicate eachother and other times it doesnt connect at all.
