Further, after updating GRASS 7 to revision 54605, I can run:

library(spgrass6)
data(meuse)
library(rgdal)
coordinates(meuse) <- ~x+y
proj4string(meuse) <- CRS("+init=epsg:28992")
library(maptools)
SG <- Sobj_SpatialGrid(meuse)$SG
td <- tempdir()
loc <- initGRASS("/home/rsb/topics/GRASS/G7svn/grass-7.0.svn", td, SG)
loc
writeVECT6(meuse, "meuse", v.in.ogr_flags="o")

without problems. My sessionInfo() output:
