Bug 410419

Application: kwin_x11 (5.16.3)

Qt Version: 5.13.0
Frameworks Version: 5.60.0
Operating System: Linux 5.2.3-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
switching between virtual desktops while the animation of a closing window (the break-into-pieces animation) was still displaying.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
