CTD on Enslave

[ldb88]

Playing as Ptolemaioi. I am sieging a Seleukid city. The enemy attacks with a different army, bringing the besieged army out as reinforcements, along with another nearby army as reinforcements. I defeat the army on the battle map, and when it gets back to the campaign map, I click enslave. Instantly, it crashes.

I've tried it twice now. I haven't tried any variations (occupy, auto resolve, etc.) yet. I'll upload the savegame somewhere.

EDIT: Here is the link to the savegame: http://rapidshare.com/files/18637235...i_ctd.sav.html
