    Bug 660067 - GIMP crashes after Wacom tablet's hot unplug
    
    Don't call gimp_input_device_store_lookup() with a NULL name. Unplug
    seems broken because we always get name == NULL, I need to fix this
    but at least it doesn't crash any longer (and the fix is generally
    correct and not a workaround).
