I've an ETOP30 subproduct with "lambert azimutal equal
area" projection which a get in "location 1", the file
WIND generate has the following information:

proj:       4
zone:       1
north:      4384500
south:      -3999500
east:       4639500
west:       -4462500
cols:       9102
rows:       8384

When a try to change of projection (to lat-lon) in
"location 2" setting my region to match the incoming
raster with g.region w=-137.8 e=-63.2 s=10 n=80 with
the following information in the WIND file:
proj:       3
zone:       1
north:      80
south:      10
east:       -63.2
west:       -137.8
cols:       9102
rows:       8384
e-w resol:  0.008196
n-s resol:  0.00834924

i get the following error:
r.proj  in=altura_00 location=grasspru2
mapset=PERMANENT dbase=/home/miguel/GRASS/ out=kk00

Input Projection Parameters: +proj=laea +a=6378137
+rf=298.257223563 +no_defs +nadgrids=conus
Input Unit Factor: 1

Output Projection Parameters: +proj=latlong +a=6378137
+rf=298.257223563 +no_defs +nadgrids=conus

Output Unit Factor: 1
ERROR: Input map is outside current region

How i can do the change in projection correctly??
The PROJ_INFO in location 1 has
name: laea
datum: WGS84
nadgrids: conus
proj: laea
ellps: WGS84
a: 6370997.
es: 0.0067686580
f: 294.9786982000
zone: 1

and in the location 2 has
name: ltln
datum: WGS84
nadgrids: conus
proj: ll
ellps: WGS84
a: 6378206.4000000004
es: 0.0067686580
f: 294.9786982000
zone: 1

I'm working in the version 6.0 beta1.
