OK, now we see that the regions are identical.
I'd like to see also the full output of
r.info rainfall
(it will give the max-min values of the raster) and also the output of
gdalinfo rainfall.tif (the original tiff file)
Perhaps then we can understand where the -NULL values are from?

Hi Sandile:
The error is popping up, apparently, because of the strange "-NULL"
value. What is -NULL??
Can you display the rainfall raster? Does it look OK (some value
everywhere?)
Perhaps run a check on the original rainfall.tif with gdalinfo to see
what range of values it is showing? Then do r.info rainfall to show
what range the GRASS raster has.

Hi,
Whats wrong with the rainfall data (rainfall.tif) if you get a DBMI-DBF
driver error when running v.rast.stats
vector=catchments
