Inexplicable crashes

[Ferocca]

Hi! Since like 6 months I am experiencing inexplicable crashes, and now I have the time to fix it.
I was playing RevDCM (and some extra leaders and civilizations added by me) for 6 months without any problems, and suddenly it started to crash to desktop for no reason. This could happen late or early in a game, but I never really finished a game since this new bug. When reloading the autosave, it always crashed on exactly the same moment again, no matter how many times you tried again.
I am not sure, but I think it has to do with the CvTechChoose.py - I have this strange bug that, if I play with Rome or Byzantine (and only with them!), I don't have an interface and at the beginning the tech advisor pops up - and I know this is caused by CvTechChoose.py.
I don't know if this bug is related to the crashes though. I could deal with it if it doesn't crash anymore but Rome and Byzantium are unplayable, I just want it to be playable again. I am a noob in debugging, but I attached the file that I hope to be useful for the helpful people here.
Thanks in advance!
P:S: My drivers are up to date and I'm using Windows7 64 bits.

If that'd help.
