ok, the bug should be fixed in r58179, at the end it was much easier 
than I thought.

Please test the v.category module, to be sure that I've not introduced 
new bugs. :-)

yes, it is particularly annoying, because the GRASS db driver is 
pretty slow copying data from one table to another. Maybe we should 
add a flag that skip to copy the attribute tables.

On the other hand, the tables are already there, we need only to link 
the geometry features to the existing table.

Anyone against this new flag/option?
