As you see you have the spurious "cat" there.

A proper connection string looks like this:

GRASS 6.4.3svn (nc_spm_08):~/grass70 > v.db.connect -p roadsmajor
Vector map <roadsmajor at PERMANENT> is connected by:
layer <1> table <roadsmajor> in database
</home/neteler/grassdata/nc_spm_08/PERMANENT/dbf/> through driver
<dbf> with key <cat>

You may reconnect the table with v.db.connect.
