[AD] Odd behaviour in X keyboard driver on RPi

[Trent Gamblin <nooskewl@xxxxxxxxxx>]

The following function:

   keysyms = XGetKeyboardMapping(system->x11display, min_keycode,
      count, &sym_per_key);

On Raspberry Pi, _sometimes_ returns 0 into sym_per_key (as seen in allegro.log) and then crashes. Other times it returns 7 and things work. Anybody got any idea what might cause this? Should I suspect it to be fixable in Allegro or report a bug somewhere else?

Thanks,
Trent
