Hi Maning, Sometimes I have the same issue, but I don't solve this on vector. Just supose you have a map where 1 is your raster-based-polygon and NULL is outside of polygon. You can use r.mapcalc to invert it, in the maner that 1 come to be your non-polygon, and NULL your polygon. So you can run r.buffer with positive value and at the end may be you need to do some kind of crossing between original and output maps.
