Comment 6 for bug 1203329

As discovered by MP in duplicate bug 1205448, we also have (at least!) one campaign where this issue will be triggered; Empire map 2.

1. Start the game.
2. Wait for the objective to build military buildings to secure your territory.
3. Build one on the eastern border, and wait for it to complete.
4. Once the building is done, you have completed the objective and since you have opened up to the east and discovered the mountains you get a new objective.

However, now that the autosaving on completing objectives is in place (bug 536507) it will first try to attempt to save the game upon completion before displaying the new dialog. This triggers the same crash. This means we will need to fix this issue before shipping build18.

We also need to play through all of campaign maps (and probably scenarios too) to make sure they are still working with all the changes which has been merged in during this release cycle.
