Subject: Missing row and column when importing raster map with r.in.gdal

Platform: other
grass obtained from: Other (CDROM etc)
grass binary for platform: Downloaded precompiled Binaries
GRASS Version: 5.0.2 (April 2003)

I tried to import a raster grid with r.in.gdal, and apparently, a row and a column is missing in the 
imported raster map (see below).

# Files and directories:
The files are located in the directory codem1nw:
dblbnd.adf

Using r.in.gdal -e ... or r.in.gdal ... location=newlocation did not change anything.
