The problem appears with vector layers that contain geometries that containing duplicate node(s), it’s considered as an invalid geometry ?
When I select all features from the bounding box of the vector layer, lines of features that has a null geometry are not selected in the attribute table (I don’t have a problem with this shapefile).

And if you spatially select all your features, are all the lines in the attribute table being selected? You haven't answered about checking geometry validity...

A simple "Save As.." to another shapefile has solved the problem.

You can check with the tool in Vector menu > Geometry tools > check geometry validity Envoyé depuis mon HTC ----- Reply message ----- De : "Nejia Ben Nasr" < <mailto:nejia.benn...@spaceyes3d.com> nejia.benn...@spaceyes3d.com> Pour : "'qgis-developer'" < <mailto:qgis-developer@lists.osgeo.org> qgis-developer@lists.osgeo.org> Objet : [Qgis-developer] Problem when using spatial index Date : mar., janv. 20, 2015 13:03 I use QGIS 2.6.1 De : qgis-developer-boun...@lists.osgeo.org [mailto:qgis-developer-boun...@lists.osgeo.org] De la part de Nejia Ben Nasr Envoyé : mardi 20 janvier 2015 09:39 À : qgis-developer Objet : [Qgis-developer] Problem when using spatial index Hi all, I load a shapefile, then I create a spatial index to maximize speed of zoom and navigate in the map. The problem is: when I zoom to any area feature appear and other doesn’t. And it seems To me that the spatial index is automatically created even when I delete the .qix file Best regards, Nejia
