 If you try to open a vector map in a Mapset different from the current it
 seems not possible to read attributes. Running the following code from
 user1 mapset of nc_spm_08

 {{{
 from grass.pygrass.vector import VectorTopo

 #counties = VectorTopo('boundary_county')
 counties = VectorTopo('boundary_county', mapset='PERMANENT')
 counties.open('r')
 first = counties[1]
 first
 first.attrs.values()
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 AttributeError: 'NoneType' object has no attribute 'values'
