Description
When making joins between a layer with geometries, to a table without geometry columns (all residing in PostGIS), if I choose to make a graduate classify with equal intervals on a numeric data field the classes are all filled with zeros. 'Preatty breaks' mode also do nothing of useful to classify, as shows no results. If I chose other classify modes it works well (Natural breaks). Happens with 1.7.4 in Windows (XP) and 1.8 master with Ubuntu 12.04 64
