Description

If more than one features of joined layer intersects any feature of target layer and option "Take summary of intersecting features" is checked (with option "Sum" for example) and joined layer contains textual fields then QGIS throws Python error console:

An error has occured while executing Python code:

Traceback (most recent call last):

Description should be: If more than one features of joined layer intersects any feature of target layer and option "Take summary of intersecting features" is checked (with option "Sum" for example) and joined layer contains fields with NULL values then QGIS throws Python error console.

no error on master/windows. Cannot try now on Linux as the last build has a problem with python.
