Config has broken __mro__

Here plainbox.impl.secure.config.Config is doing some magic in its meta-class that results in __mro__ to consist of [description, _del_section, object] which is totally crazy. Should have a look at what is going on there.

This might be an upstream python3.2 bug, see https://plus.google.com/116315264177593873442/posts/aMYRMCW9rgc

This was actually fixed a long time ago, the code that computed the meta-class was overwriting the name and everything started to look broken.
