With the addition of the locate-pointer special keybinding (defaults to the [Control] key), we have now two separate special modifier keys which can be triggered separately, one for the locate-pointer action and another one for overlay. When processing those special modifier keys, mutter must ensure that the key was pressed alone, being a modifier, the key could otherwise be part of another key combo. As result, if both special modifiers keys are pressed simultaneously, mutter will try to trigger the function for the second key being pressed, and since those special modifier keys have no default handler function set, that will crash mutter. Check if the handler has a function associated and treat the keybinding as not found if no handler function is set, as with the special modifier keys. https://gitlab.gnome.org/GNOME/mutter/issues/823
Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
