kwin wayland backtrace

If I minimise Firefox and then click on it's icon in the task manager to restore, kwin crashes.

This seems to happen only if I click while the thumbnail image of Firefox is being displayed, and before it's fully displayed.

I cannot trigger the crash with other applications (tried Dolphin and Libreoffice)

Backtrace is attached.
