[Qgis-developer] $scale not evaluated

Hi again, 
the very usefull $scale variable seems to be not evaluated everywhere in
QGIS interface.

- in Dufour 2.0, only label expression seem to get the value

- in master, label expression and data defined symbol properties have it,
but ruled based renderer gets nothing . 
Anyone has this behaviour? 

Is there any workaround in QGIS 2.0 to show/hide feature based on their
screen size. I use ($length / $scale) > threshold but $scale is broken ..
