OK, removed.

I have also found a trick for the confusing error message. Now it looks
like this:

GRASS 6.3.cvs (spearfish60):~ > g.copy vect=roads,random --o
Copy vector <roads at PERMANENT> to current mapset as <random>
WARNING: The vector 'random' already exists and will be overwritten.

GRASS 6.3.cvs (spearfish60):~ > v.db.droptable random
Removing table <random> linked to layer <1> of vector map <random>
You must use the force flag to actually remove the table. Exiting.

GRASS 6.3.cvs (spearfish60):~ > v.db.droptable random -f
Removing table <random> linked to layer <1> of vector map <random>
Dropping table <random>...
Current attribute table link(s):
(No database links remaining)

This should solve all problems mentioned in the bug report.
