QGIS and GRASS devs, Below I'm forwarding you a QGIS-GRASS issue. It seems to be somewhat related to https://trac.osgeo.org/qgis/ticket/554#comment:7.

I am editing a dbf file of a GRASS vector in QGIS. When I launch the open attribute table in QGIS it shows a long table of over a thousand records, but when I open the file in OpenOffice Calc 3.0 it only shows me 30 records which was the 30 classes I initially converted from raster to vector. Using: r.to.vect -v input=x output=x_vect feature=area --overwrite --verbose My plan is to edit the class categoris of each vector polygon in OOCalc. Any ideas why is it like this? I don't have problems with my previous vector files when I am using 6.3
You used the '-v' switch which means: "Use raster values as categories instead of unique sequence". Thus, it is normal that the output table has only that many rows, as many unique cell values were there in the input raster map. Multiple polygons are linked to the same table row (by having the same category), so there are more polygons than rows in the table indeed. QGIS table editor does not present a GRASS vector map table as it really is, but treats each vector feature separately. This has the pro that you can access individual polygons from the table editor, no matter that multiple polygons have the same category. The con is that it's not the real table as it is, which confuses some users. Best if QGIS could provide both modes, with the current behaviour as an option and defaulting to real table layout.
