Comment (by mmetz):

 Replying to [ticket:3407 mikatt]:
 > GRASS 7.2.1 (on Linux Mint 18) produces an error when trying to read in
 ESRI shapefiles that have empty cells. This used to work fine until
 recently, and I have no problems with GRASS 7.2.0 on Windows 7.

 What are the GDAL/OGR versions?

 Thanks for the example, I could reproduce the error.

 This is a GDAL/OGR issue. As of GDAL 2.2, `OGR_F_IsFieldSet()` apparently
 returns true even if the field is empty, and `OGR_F_GetFieldAsString()`
 returns a zero-length string (not NULL) for an empty field.

 v.in.ogr has been fixed in r71431,2 (trunk, relbr72) to account for the
 new behaviour of GDAL 2.2, supporting older versions of GDAL.
