Bug ID: 427338
Summary: Kate crashes when toggling the "LSP Client" plug-in
Product: kate
Version: 19.12.3
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: ser...@cip.md
Target Milestone: ---
Application: kate (19.12.3)
Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-48-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Click the checkbox next to "LSP Client" repeatedly, about 2 clicks per second.
I also had Kate crash when not clicking the checkbox repeatedly but instead
changing to another setting group and then back to "Plug-ins" after enabling
"LSP Client", but those crashes are harder to reproduce.
The crash can be reproduced every time.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
