Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 5.10.0-0.bpo.5-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:
this device: nothing
phone 1 (oppo reno 2z, colorOS 11.1): started local musicplayer, with no DLNA action or other network request
phone 2 (motorola xplay, android 7.1.1): nothing
- Custom settings of the application:
there are 2 phone devices connected to the kdeconnectd, phone 1 (oppo reno 2z, colorOS 11.1) and phone 2 (motorola xplay, android 7.1.1)
debian 10.10 with kernel 5.10.0-0.bpo.5-amd64

The crash does not seem to be reproducible.
