        <pre>Ha, it's not that as I suspected, but one I'd forgot I'd enabled:
Ctrl+Alt+Backspace to kill the X server.

This changes backspace to:
    type "CTRL+ALT" {
        modifiers= Shift+Control+Alt+LevelThree;
        map[Shift]= Level2;
        preserve[Shift]= Shift;
        map[LevelThree]= Level3;
        map[Shift+LevelThree]= Level4;
        preserve[Shift+LevelThree]= Shift;
        map[Control+Alt]= Level5;
        level_name[Level1]= "Base";
        level_name[Level2]= "Shift";
        level_name[Level3]= "Alt Base";
        level_name[Level4]= "Shift Alt";
        level_name[Level5]= "Ctrl+Alt";
    };
    key <BKSP> {
        type= "CTRL+ALT",
        symbols[Group1]= [       BackSpace,       BackSpace,        NoSymbol,  
     NoSymbol, Terminate_Server ]
    };

This shouldn't make a difference, as Ctrl+BackSpace will generate backspace,
but it's exactly this issue:
<a href="https://github.com/xkbcommon/libxkbcommon/issues/17">https://github.com/xkbcommon/libxkbcommon/issues/17</a>

I still think it should get fixed in GTK+. But for the meantime, adding an
explicit map for both Control and Control+Shift to Level1, with preserve
entries for both, 'fixes' it.</pre>
