-- Information about the crash:
My Alt+F7/F8 shortcuts for moving/resizing windows are suddenly missing, and I couldn't figure out how to re-establish those shortcuts in systemsettings/shortcuts, so I thought I'd try to see if there was anything different in "Configure Window Manager..."

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
