Bug ID: 449702
Summary: KWin crashes when closing a grouped application
Product: kwin
Version: 5.23.5
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: k...@huftis.org
Target Milestone: ---
Application: kwin_x11 (5.23.5)
Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.16.4-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.5 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
Closing a bunch of application instances by right-clicking on the icon for the
application group and selecting ‘Close’. Audacity was the application. After
answering ‘No’ on the ‘Save project before closing?’ dialog that pops up in one
of the instances, KWin consistently crashes.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized
out>}
