Since I have a day off today I thought I'd take a look at how C2C had changed in the last year or so, so I attempted to update top the latest SVN and start a (single player, custom, but with defaults) game. However, I have not been able to get it to work (I get no UI so the game cannot be played - just have map with units, but nothing else).
See screenshot - also two Python stack dumps during first turn initialization (as per screenshot). I suspect the one whinging about missing widget types is the key issue...?
