Bug ID: 426939
Summary: Kate sometimes crashes when showing previously-hidden
menu bar
Product: kate
Version: 20.08.1
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: s_chriscoll...@hotmail.com
Target Milestone: ---
Application: kate (20.08.1)
Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: Linux 5.4.67-xanmod1 x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.19
-- Information about the crash:
- What I was doing when the application crashed: I came back to my computer
after a long period of inactivity, clicked on my open Kate window which had
some notes in the default "untitled" document. I then pressed Ctrl-M to show
the menu bar, which had previously been hidden. That is when Kate crashed. This
also happened to me the other day in a similar situation (Kate had been open a
long time, came back to computer, Ctrl-M to show menu bar). These two instances
are the only times thus far where I have encountered the crash. Ctrl-M in Kate
usually functions without issue for me.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
