<div dir="ltr"><div>Hi dev,<br><br>I'm using qgis master and I'm trying to use the difference tool between two layers (from the vector menu and processing).<br><br></div><div>On the map canvas, the result looks fine, I get less features displayed.<br></div><div>However my result layer contains exactly the same number of features than my original layer.<br><br></div><div>Running the "check validity" from processing, I get a lot of "Unknown geometry type 0".<br></div><div>I can't use this layer in any processing algorithm : <br>
<p style="margin:0px;text-indent:0px">"QgsFeature.setGeometry(QgsGeometry): argument 1 has unexpected type 'NoneType'"</p><br></div><div>I don't know which algorithms may be affected by this kind of bug.<br></div><div><br></div><div>It's working fine on qgis 2.8.<br><br></div><div>Regards,<br></div><div>Etienne<br></div></div>
