Thanks for your quick reply!
It would be nice if there was a stable working version that I could run; I don't think I need the very latest fancy features.
I can give you access to my guest machine for debugging, if it would help: I'm running a dedicated server with KVM virtualization just for cases like this: to try out new software without fear of breaking the production servers that need to be running. If you need access to my box, please reply to my email.
