[Freeciv-Dev] (PR#3024) Crash when starting a 2nd game with client

["Guest via RT" <rt@xxxxxxxxxxxxxx>]

I played a game and died early on.  After death, I press End Turn twice
until it was greyed out.  I quit civserver and started a new game,
leaving the civclient running.  I reconnected the client, chose my
nation, and when I pressed ok, I got a segmentation fault.  It occurred
right after the e_nation_selected message:

3: Neither of tags e_nation_selected or (null) found
Segmentation fault (core dumped)

I tried the same situation (dying then connecting to a new game from the
same client) twice more, and it crashed once.  The core (1MB) is at
http://kenn-michelle.ca:8080/freeciv/core2.gz, but here is the (long)
backtrace:

I'm using CVS from Feb 1, gtk2 client on Red Hat 8.
