Comment (by hamish):

 and looking at an all-NULL map in GRASS 6.5 which was created in 6.4 or 7:

 {{{
 G65> r.univar nullmap7
  100%
 total null and non-null cells: 2654802
 total null cells: 0

 Of the non-null cells:
 ----------------------
 n: 2654802
 minimum: -2.14748e+09
 maximum: -2.14748e+09
 range: 0
 mean: -2.14748e+09
 mean of absolute values: 2.14748e+09
 standard deviation: 0
 variance: 0
 variation coefficient: -0 %
 sum: -5701143883677696
 }}}

 ouch.
