[GRASS-user] problems with r.to.rast3elev

Hello all,

I'm experiencing some issues with r.to.rast3elev , that I didn't had before.
I'm trying to reprocess some volume calculation
on dune fields in southern Brazil (see this:
http://geomorphometry.org/Grohmann2011) so I can evolve what I presented in
the Geomorphometry Meeting into a full paper, but at this point I can't
calculate the volumes any more!

(BTW, Helena, I'm thinking about comparing the volumes from r.volume and
r.to.rast3elev, since I think there will be differences..)

OS: Linux, Ubuntu 11.04
In GRASS 6.4.1, installed from Ubuntu repositories, I got this (running
inside a python session):

 grass.run_command('r.to.rast3elev', input=clump, elevation=dem,
output=dem3d, lower=1, overwrite=True)
Creating 3D raster map
ERROR: G3d_cache_hash_remove_name: name not in hashtable

and in GRASS 7.0svn updated today, I got a segmentation fault.

the region is set to match the 'clump' map (which is the same as the mask,
to limit the calculations to the active dunes).

any help is appreciated
