Bug ID: 422615
Summary: kde connect deamon crashes on clicking
'Laserpointer'-Button in Presentation Mode
Product: kdeconnect
Version: unspecified
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: common
Assignee: albertv...@gmail.com
Reporter: danielwohl...@gmx.de
Target Milestone: ---
Application: kdeconnectd (1.4.0)
Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.3.0-53-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18
-- Information about the crash:
- What I was doing when the application crashed:
I have KDEConnect installed on my Huawei P30 Pro and connected via WiFi to the
KDEConnect-Deamon on my kde neon linux.
Every time i try the Laserpointer-Button on the Presentation-Remotecontrol it
crashes the deamon.
Interestingly this does not happen when I'm connected to KDEConnect for windows
on my gaming rig.
The crash can be reproduced every time.
-- Backtrace:
Application: KDE-Connect-Dienst (kdeconnectd), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
