Subject: d.grid -g fails for Washington State Plane South Projection

Platform: GNU/Linux/x86
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: 20060117

Problem: d.grid -g fails to draw a geographic grid in the Washington State Plane South projection:

d.grid -g works perfectly from Washington State Plane North (same projection with the standard parallels shifted north):

(draws grid on screen)

To reproduce the error you need to create a washington state plane south location.

Select Projection: D (other projection)
projection: stp
datum: nad83
transformation: 5 (Washington - Oregon)
state FIPS code: 53 (WA)
county FIPS code: 67 (Thurston)
state plane: 83 (1983)
units: 1 (US Survey Foot)

north:      1383333.33333333
south:      -90000
west:       478678.67867868
east:       2681081.08108108
nsres:      303.03030303
ewres:      300.3003003
rows:       4862
cols:       7334

Now try to add the geographic grid.
