[Freeciv-Dev] (PR#9780) server crash caused by gui-xaw

This one looks serious.  Using the xaw client will cause the server to 
crash.  It's probably two bugs, in server and client.  It happened the 
turn after I achieved my tech goal, when the tech was still unset (I guess).

civserver: ../../freeciv/server/plrhand.c:280: found_new_tech: Assertion 
`plr->research.researching != (200-1)' failed.
