Hi Markus
I realized that I sent this email to the wrong mailing list. Here goes:


I believe it's ok:
projection: 1 (UTM)
zone:       -24
datum:      wgs84
ellipsoid:  wgs84
north:      9305500.00000001
south:      9095770.00000001
west:       444000
east:       689130
nsres:      30
ewres:      30
rows:       6991
cols:       8171
cells:      57123461

And my raster is:
|   Type of Map:  raster               Number of Categories:
3               |
  |   Data Type:
CELL                                                       |
  |   Rows:
6991                                                       |
  |   Columns:
8171                                                       |
  |   Total Cells:
57123461                                                   |
  |        Projection: UTM (zone
-24)                                          |
  |            N: 9305500.00000001    S: 9095770.00000001   Res:
30         |
  |            E:     689130    W:     444000   Res:
30                     |
  |   Range of data:    min = 0  max =
3                                       |

So it matches. What might be causing this error/bug?
