Bug ID: 454054
Summary: when I pair with my own kdeconnect daemon, it crash
Product: kdeconnect
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: common
Assignee: albertv...@gmail.com
Reporter: meruhk2...@gmail.com
Target Milestone: ---
Application: kdeconnectd (21.12.2)
Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.17.7-1.surface.fc36.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora release 36 (Thirty Six)"
DrKonqi: 5.24.5 [KCrashBackend]
-- Information about the crash:
- Unusual behavior I noticed:
I use kde-connect on plasma and gnome, I auto start it it by gnome settings and
systemctl service.
I also auto start by KDE-plasma
(/etc/xdg/autostart/org.kde.kdeconnect.daemon.desktop)
Before I update to Fedora 35, I set my PC name as F35, also set kde-connect
name as F35. After I updated to Fedora 36, I change both to 36.
However, when I opened "KDE-Connect Settings" on PC, the old one "F35" appears
on the list. Which is very weird, I shouldn't be able to connect to my PC from
my PC. So when I click pair with "F35"
The kde daemon crashed. (/usr/libexec/kdeconnectd)
The crash can be reproduced every time.
