Bug ID: 429402
Summary: Plasmaconnect still crashes when using pointer button
in slideshow menu
Product: kdeconnect
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: common
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kdeconnectd (1.4.0)
Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-54-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I was exploring the slideshow menu of the kdeconnect App on my Samsung S8 when
I tapped on the button labeled "Pointer".
This let to kdeconnectd crashing instantly.
I tried this multiple times (at least 10) and it crashes every time.
There seem to be multiple similar reports, however the issue is reported fixed,
which is obviously not the case (did the bug reappear in a later update maybe?)
I hope you will take the time to try and fix this or at least give me advice on
how to fix it on my end.
The crash can be reproduced every time.
