Version: (using KDE Devel) Installed from: Compiled sources Compiler: gcc OS: Linux When a shortcut is modified, a contextual menu appears under the action, probing for re-assigning a new shortcut to the action. After modifying the shortcut, this contextual menu must be closed, otherwise it remains on the screen, and it is not possible to modify other categories of shortcuts (as they are hidden behind this contextual menu).
+1. I had the same problem and got a crash when changed the application selection (eg: from krunner to kwin).
Fixed in more recent version.
