Missing Geometry in last row of some shapefile

QGIS considers a null geometry for the last row of some shapefiles (generated by a 3rd party software, see sample in attachment), but is visible in the attribute table.

Other programs (ArcGIS, Openwind) read the shapefile correclty, so it can be assumed that it a QGIS issue.

The error from GDAL is this:

ERROR 1: Error in fread() reading object of size 32 at offset 212 from .shp file

The issue feels similar to https://trac.osgeo.org/gdal/ticket/4203 but that one is fixed. However, I believe that the 3rd party software makes invalid shapefiles. A workaround that probably works is to
  1. delete the .shx file
  2. re-create .shx with ogrinfo

ogrinfo test_layout.shp -al --config SHAPE_RESTORE_SHX true

  • Resolution set to up/downstream
  • Status changed from Open to Closed

Not a QGIS issue - this needs to be fixed in either GDAL's reading of the file or in the application which created the invalid shapefile.
