[Freeciv-Dev] (PR#7216) take again client crash

["Per I. Mathisen" <per@xxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=7216 >

You crash the client (gtk2, CVS HEAD) by doing 'take' twice.

To reproduce:
Start savegame. Login as 'me', then 'take me player1'.
Then 'take me player2'.
*booom*

gdb output:

Program received signal SIGSEGV, Segmentation fault.
