commit 7018f280406eb0ef899a4046de274cfdd582881b
Author: Peter Hutterer <peter at cs.unisa.edu.au>

    xkb: when copying the keymap, make sure the structs default to 0/NULL.
    
    It actually does help if a pointer is NULL rather than pointing to nirvana
    when you're trying to free it lateron. Who would have thought?
