Bug report #11562

Crash after using memory data provider in python and adding the layer to the layer registry

Added by Thilo Schneider almost 6 years ago. Updated almost 6 years ago.

Status:Closed
Priority:Severe/Regression
Assignee:-
Category:PyQGIS Console
Affected QGIS version:2.6.0 Regression?:No
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:
Crashes QGIS or corrupts data:Yes Copied to github as #:19827

Description

The following code creates an immediate crash when inserted into the python console:


vectorlayer = QgsVectorLayer("Point?crs=epsg:31467", "Player", "memory")
vectorlayer.updateExtents()
QgsMapLayerRegistry.instance().addMapLayer(vectorlayer)

If one first adds the vectorlayer to the layer registry and then updates the extends, QGis crashes not immediately but as soon as the map is redrawn the next time. The crash persists if I add features to the layer before adding it to the layer registry.

All third party plugins are disabled in my installation. The same code has been working in 2.4.

Yes, could you try to run QGIS with the --noplugins option, please?

Problem solved. It turned out that I had an old dependency installed on my system.
