Bug ID: 411251
Summary: KWin crashed while navigating with keyboard shortcuts
Product: kwin
Version: 5.16.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: the.fed...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.16.4)
Qt Version: 5.13.0
Frameworks Version: 5.61.0
Operating System: Linux 5.2.9-arch1-1-ARCH x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Switched desktops with keyboard shortcut (Ctrl+Alt+arrow), then changed music
in Gnome Music Player Client 11.8.16 with keyboard shortcut (Ctrl+Right Arrow).
All greebles and panels disappeared from desktop, then KWin restarted
automatically at the first virtual desktop, with no apparent harm.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
