may be a bug reading grass files

[Francisco Alonso]

Hi:

I have had a problem to read a GRASS file with a mapscript application.

After some struggle I have realized that the problem was that:

-A GRASS CELL raster file incluiding cells with a 0 value and with a colr file 
cannot be  read. 

Actually after add a 1 to all the cells (it was 0-254 file) and adjust the 
colr file I could read it properly.

I don't know if there are previous reports about this or if it is a real bug.

Cheers
