the command is launched with python executable:

.../python.exe d.rast3d.py

so it seems that it expects the full path to the script and therefore chdir
before it made it work.
$GISBASE/etc/gui/scripts/  is already on the PATH.

there should be d.rast3d.py which is really there so that's not the problem.

So we can keep this solution until someone finds something better.
