Bug 432466

Application: kdeconnectd (1.4.0)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.11-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 33 (Thirty Three)"

-- Information about the crash:
- What I was doing when the application crashed:

I was working on the computer, but not interacting with KDE Connect nor with the phone.
It was a crash out of the blue.

The phone was charging, and also I was in the middle of a call (using a bluetooth headphone paired to the phone).
But both of those events were started more than 10 minutes before the crash so I think it's unlikely they are related to the crash.

The phone has Android version 10, and the KDE Connect app on it is at version 1.16.0.

-- Backtrace:
Application: KDE-Connect-Dienst (kdeconnectd), signal: Segmentation fault
