Comment:
I couldn't reproduce the crash, but from the backtrace it seems like it's crashing when sorting of the players dialog is automatically triggered from changes made in plr_report::update_report(). Attaching a patch (for S3_0) that I guess could help (makes sure that new player from civil war is properly included to the report before trying to sort it in inconsistent state).

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

>
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.
