Hi Anita, I'm running master here, and using Rulebased Renderer in a python plugin.
But I can add rules, and for every rule I can open the style and then add other symbol layers...
(trying with polygons here...)
What do you mean with 'not possible to activate'?

Sorry, I meant symbol levels not layers.

There are related tickets #3222 #3039 #2832 with quite discussions. There were some more discussions on the dev mailing list.
I am somehow reluctant to enable usage of symbol levels for rule-based renderer because this would limit us to one rule per feature. For qgis 1.7.0 it was decided to apply a patch that allows symbol levels for rule-based renderer. But for longer term (qgis 2.0) I would like to see a different approach of defining rules similar to SLD.

If it's a conscious decision to not allow symbol levels in rule based renderer, I think the button should be greyed out. Otherwise users start to wonder why it simply does not work.
I'll close this as duplicate of #3039
