Comment:
It is repeatable. If I start afresh (even after a new git pull which compiles quite a lot - now on XXX), start a server, load turn-81, start client and connect, play some moves, hit End Turn, see the civil war message, play some moves, click on Nations and get another core dump. I've managed to do it a few times, but can't find an exactly repeatable sequence.
It looks identical to me, but I'll include it ('cos it's so easy to do):
Core was generated by `./client/freeciv-qt'.

Ticket details:
I hit End Turn; I saw in the (qt) message box something about a civil war, and then the qt client disappeared with a core dump. I had the above version plus cazfi's trade-route-bonus patch and alain's more-columns-in-Nations patch.
The server seemed cool and it's console sed:
Game saved as freeciv-T0080-Y-0525-auto.sav.xz
>
Game saved as freeciv-T0081-Y-0500-auto.sav.xz
>
Player 'Milton Cato' now has AI skill level 'Hard'.
Game saved as freeciv-T0082-Y-0475-auto.sav.xz
>
2: Lost connection: chippo from localhost (client disconnected) (player Petar Krešimir IV).
Reconnecting, endgames, load games, restarting server all do not repeat the core dump, but I will attach that turn 81 savegame, anyway.
Backtrace:
Core was generated by `./client/freeciv-qt'.
Program terminated with signal SIGSEGV, Segmentation fault.

Just before the core dump, I was thinking:
Civil War! I have Marco Polo's!
There was some bug regarding having Marco Polo's and the meeting of the new player. Now is a good time to see whether that bug is fixed.
But then the core dump happened. And then I remembered that the marco-new-player bug didn't cause a core dump, was resolved after another turn and was seen under gtk.
