Comment:

 Still seeing this problem - here is my exact workflow:

 r.external in=N61E043_small_nd.tif out=N61E043_small_nd
 g.region -a n=62.0087569444 s=60.9912430556 w=42.9912430556
 e=44.0087569444
 r.mapcalc "temp_null=if(isnull(N61E043_small_nd),1,null())"

 I should be seeing a continuous ring of nodata around the raster.  Instead
 I get the first and last row, and none of the first and last column
 (except those pixels in the first and last row).

 If I run r.in.gdal, the routine works as expected.
