After defending the base (where there are no civilians) the game shuts down with the message
ufo: src/client/campaign/cp_campaign.c:388: CL_HandleNationData: Assertion `civilianSum > 0' failed.
./ufo(Sys_Backtrace+0x1f)[0x819e6b6]
The last part of the game log (from the terminal) is attached

System:
===============
Ubuntu Karmic..
Nvidia something graphics, proprietary driver (version 185)
i386

What happened before the bug occurred? Is the bug reproducible?
=====================================================
Defended the base several times, but a certain attack (arriving in-game a couple of hours after a certain save) crashes every time
So it is definitely reproduceable
The battle it self has some issue with aliens appearing on top of the soldiers, but that has happened before

Hope this helps any

This is because the current scoring algorithm is purely based on the amount of civilians you save. No civilians means a divide by zero, which is why the assert is there. I will implement a hack to prevent this from happening, but what we really need is a simple "mission objectives" system that intelligently calculates a score based on the mission's objectives.

The asserts are gone in r29028. Note that this revision fixes the symptoms, not the underlying cause. Nevertheless, I consider this bug closed.
