Thanks for the update. I went through the code and things look good. I have
only one concern: QgsGeometry instances stored in QVariant do not seem to
be released... When "$geometry" is used, then it's returning the instance
from the feature (which should not be deleted), but temporary geometries
constructed from wkt/gml must be deleted.

Maybe we should store directly QgsGeometry object instead of just a pointer
inside?

Martin
