I had to apply it by hand for some reason (I'm not running -mm1 if that makes 
a difference), but it's fixed the problem :)

Many Thanks

This is the root cause. See http://bugme.osdl.org/show_bug.cgi?id=1716,
there is also a fix patch available.

Thanks for pinpointing it, i've posted a simple patch in the hopes that
it's sufficient.
