Amazing that there is so helpful people around here but have to say something.

"If you want to play with extras-devel software you need to be prepared to feel some pain sooner or later. "

"PLEASE PLEASE PLEASE don't play with it unless you really know what you are doing. Be ready to file proper bug reports instead of posting complaints. "

But everything went quite nicely. Just to remember some users that if you play with devel BE PREPARED!
