Thanks Kit,

We found that bug yesterday and it is indeed what bit us.
The bugreport says the fix landed for 1.8.1.1. Our servers were
running 1.8.1.1 and the clients were on 1.8.1.

We've tested a few clients with the 1.8.1.1 version and it works just
fine so I'm in the process of rolling out the upgraded rpms.

Thanks for helping out!

Erik
