Copying Alexander Wirt here again, as I think this is his patch.
I'll skip this patch in my next resend...

I'll update the patch to mention this.

Since I'm no superhacker, I was afraid to touch anything else then the
things I could test and this change is what's needed to fix the reported
bug. (Actually only one of them was needed IIRC, but it would be stupid
to only change one.)
I'll have a look at the other helper functions as well, probably adding
a separate patch so that it can be easily dropped if I screw something
up there.. :)

I'll also drop the mpath stuff you mentioned in the other mail...

Thanks for reviewing the patches!
