[Xmonad] Bug Reports: changing X keymaps disrupts xmonad keybindings

G'day. Just a quick bug report: Changing X keymaps between, say, dvorak and us, using setxkbmap will often (though not always) break xmonad keybindings. I haven't been able to discern any pattern with when it will break the bindings and when it won't. Getting keybingings to work again is as simple as using setxkbmap over and over until the keybindings work again. ie setkbmap will break the bindings, but it will also fix them when they're broken. Another bug report (though one which has probably been noticed by someone else): killing xmonad and restarting it seems to lose management of all windows that are not being managed by workspaces currently visible on any screens.
