When using the v.distance module the user is provided with a "(optional) column to read labels" parameter.

It turns that this parameter ("to_column") must be a varchar() column of the "to=" map, but if such column does not exist (or it is not selected) then the module fails

C:\\>v.distance from=pontos@etrs89 from_layer=1 to=ferro@etrs89 to_type=line to_l
ayer=1 upload=dist to_column= column=dis dmax=-1 dmin=-1

GRASS_INFO_ERROR(3352,1): Column <> not found in table <ferro>
GRASS_INFO_END(3352,1)

so in the QGIS interface/console it is not optional at all.

In the native GRASS GUI the module work as expected when no "to_column" is chosen

@v.distance from=pontos@etrs89 to=ferro@etrs89 to_type=line,area upload=dist column=dis@

and still works when it is optionally chosen

@v.distance from=pontos@etrs89 to=ferro@etrs89 to_type=line,area upload=dist column=dis to_column=ciao
