[GRASS-user] v.overlay not working?

Hi all.
v.overlay fails on some specific layers:
===
v.overlay ainput=liguria_agricola at alessandra atype=area alayer=1
binput=uso_suolo_agricolo at alessandra btype=area blayer=1 output=over_xor operator=xor

Collecting input attributes...
DBMI-DBF driver error:
Cannot create dbf database: cat /home/paolo/Desktop/spezia/grass/spezia/alessandra/dbf/
===
I suspect this is due to the precence of duplicated CATs in one of the origin layers.
So the questions are:
* how to rearrange CATs, removing duplicates (but keeping all the geometries)?
* does anybody confirm this behaviour?
* I think it should fail more gracefully; should I file a ticket?
Thanks a lot.
