Bug ID: 407962
Summary: kdeconnectd crash at network connection loss
Product: kdeconnect
Version: 1.3.4
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: albertv...@gmail.com

kdeconnectd-20190526-150946.kcrash.txt
It has happened twice today that kdeconnect crashed after the network
connection went down. I currently rely on using my cellphone as LTE hotspot,
first it ran out of battery, the second time I simply left for a break and shut
down the hotspot for that. At the second time I had prepared kdeconnect with
debug symbols.
STEPS TO REPRODUCE
1. Create WiFi hotspot with (kdeconnect-paired)phone
2. Connect to WiFi hotspot
3. Shutdown WiFi hotspot
4. Look at drkonqi's grim systray face
