[Darin Miller]

Launched KDE connect on the phone. Verified the PC could see the phone. Hour or so later kdeconnect crashed without any further interaction. Computer was awake the entire time.

Status changed to 'Confirmed' because the bug affects multiple users.

KDE connect has not crashed since I filed this bug report (at least not that I remember). I would like to close it as "fixed".
