Sentry Crash Report:

Description Martin Walch 2013-05-14 01:48:49 UTC

Application: konquest (2.1)
KDE Platform Version: 4.10.3 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.8.12-gentoo-gnu x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:
I made konquest crash by manually sending SIGSEGV

- Custom settings of the application:
1. start konquest
2. New
3. manually make all planets neutral or vacant
4. OK

Now konquest is in an infinite loop eating one cpu.

The crash can be reproduced every time.

-- Backtrace:
Application: Konquest (konquest), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Nemanja Hirsl 2013-10-27 12:47:19 UTC

Git commit 90768a71eaa68de1182e78b71b572e707a712a26 by Nemanja Hirsl, on behalf of Alexander Schuch.
Committed on 27/10/2013 at 12:42.
Pushed by nhirsl into branch 'master'.

The game will never end if none of the players has any planets. This
patch makes sure that the game can only be started if all non-spectator
players do have at least one planet.

Some internal variables are renamed to make the name match their
content/purpose much better.
