Identify panel: clicking on a curved line doesn't always show the radius

If you click on a curved line using the info tool, QGIS will now display the radius in the info tool.
Using master, actually, QGIS shows the radius only if the closest vertex is the one at the "middle" of the curved section. Clicking closer to the start or end points of the curved section doesn't return radius.
Though the Identify results panel labels this information as Closest vertex radius I think that clicking anywhere on the curved line section should return a Closest line (section) radius (or something like that) rather than nothing. Information should be picked from the line geometry rather than the closest point.
