QGIS » QGIS Application

If I copy and paste the style from one layer to another, I get an error stating 'nextFeature() without select()' and the polygons disappear from the map. Whenever I pan or zoom on the map, another error is added to the log messages screen under the postgis tab.

If I save the project and then remove the section shown below from the project in Notepad++, when I reopen the project the polygons display and no errors.

The data is coming from a query that was loaded using the DB Manager plugins SQL window. The base data lives in a PostGIS database.
