@SO,
No, No Rev I have it Off.
After turning the Python Popup off at the end of the turn I went to the southern area of my empire where the Dragon ships have been poaching my work boats. I attacked with Galleys and destroyed 2 Dragons. I then clicked on Red button for EoT and just after the running man appeared I CTD'd. Savegame and Minidump attached. SVN version 5118 is my current version.

Minidump shows this is the same crash as reported a little earlier, to which I think I have a fix. I will run an end-turn on your save as part of my testing before I push to SVN though.
