floating point exception upon d.rast?

[Luc Boerboom]

Many thanks to the people that helped me with my color problems earlier
this week. In the next step I have the folowing problem:

I have saved a raster DEM from ARCINFO in GRASSformat, and put the cell
relate d folders in PERMANENT in my location. After opening a monitor I
give the d.rast (filename) command. As response I get: floating point
exception.

I couldn't find an answer in reference manual, programmers guide and my
UNIX docs? Where do I look for this? What's going on?

Thanks for your help!! Luc
