Bug 449702

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>}
