[GRASSLIST:5289] segmentation fault with v.overlay

[Marta Benito]

Hi, I am trying to overlay to vectorial (area) maps, mapa1 and mapa2 but
without success: 
# v.db.connect -p mapa1
Vector map <mapa1> is connected by:
field <1> table <mapa1> in database
</home/marta/grassdata/espanya_modelo_devel/pred_ppinea/dbf/> through
driver <dbf> with
key <cat>
# v.db.connect -p mapa2
Vector map <mapa2> is connected by:
field <1> table <mapa2> in database
</home/marta/grassdata/espanya_modelo_devel/pred_ppinea/dbf/> through
driver <dbf> with
key <cat>

BUT:

# v.overlay ainput=mapa1 binput=mapa2 output=output operator=and

Any ideas?
