    work aroud crash caused by LED device handling

    During suspend led device is removed; during resume it is recreated.
    Apparently removing led device cause hald-addon- leds to exit
    (thus disconnecting D-Bus connection); and sometimes next "add" 
event
    comes too early, before hald had chance to notice missing addon.

    Adds extra check to hald_singleton_device_added() to ensure we do 
not
    abort on disconnected D-Bus connection.
