This is PR#1259, which has been erroneously marked as "fixed". See 
http://www.freeciv.org/cgi-bin/bugs/fixed?id=1259;user=guest;selectid=1259#followup2
 
for my explanation of the problem (which I can only assume was ignored at 
the time ;)

To reproduce:

1. Start a CVS server normally.
2. Start a CVS client with differing capabilities to the server. e.g.
   FREECIV_CAPS="+1.11.6 conn_info pop_cost turn (etc.)" ./civ
3. Oh dear...

        The fix: rewrite the agents code so that it doesn't render 
capabilities completely useless.
