I've been having a reproducable crash in my game as the Vaulters on Windows 7, playing Endless Space Disharmony v. 1.1.58.

Here is the crash report file:

and the save:

To reproduce the crash, hit the "complete fleet movements" button and wait for the pirate attack. The game crashes right at the start of the battle on manual.
