Added by Giovanni Manghi over 11 years ago. Updated over 11 years ago.

Status:	Closed
Priority:	Severe/Regression
Assignee:	-
Category:	Web Services clients/WFS
Affected QGIS version:	master	Regression?:	No

Crashes QGIS or corrupts data:	Yes	Copied to github as #:	16843

Description

pick this shape: http://thematicmapping.org/downloads/TM_WORLD_BORDERS-0.3.zip

and publish it as WFS layer with QGIS server, then use qgis as wfs client and add this wfs layer, then identify a feature it will give instant crash:

#3 Updated by Jürgen Fischer over 11 years ago
