  Since we get this kind of patch very regularly, I think it's time we 
commit it :-)

Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout at mind.be>
Tested-by: Arnout Vandecappelle (Essensium/Mind) <arnout at mind.be>

  Note: the patch needs to be refreshed against master; sending an update 
in reply.

  Arnout
