I'd call it a 'semi-constant' crash... It seems to be caused by similar things every time, just not always at the SAME time (same turn).
How to describe it...
For starters, it doesn't happen on AI 'turns' - only when a limited set of 'manipulations' occur during my own turn...
Well, Here is an example: the 'leader/diplomacy' screens, without the mod they work fine, all images, all animations. But with the mod activated, the screen is bugged, either failing to animate (frozen image, but functional), or the image wont appear at all, being replaced by a screen full of red/white 'checks' (again, all the buttons still work). Sometimes, I'll have a similar issue when I go into the city-view screen and try to re-assign my workers - 'yield' info tool-tips that are fine normally, now are replaced by a small block of the red/white checks... Also, when a great-person is spawned, sometimes their icon wont appear in the pop-up...
All these glitches seem likely to be manifestations of the same things that are causing the crashes... I wish I could give you more info, but I don't get 'error messages' when the game crashes... Just BAM! back to desktop...
I *did* get an error-box ONCE, but it was only visible for a moment before I reverted to desktop, so I wasn't able to read it (let alone take a screen-shot)... All I got was something about a 'texture' file not being found...
SCREENSHOTS:
Leader screen (worst case):

PS: I doubt it matters, but I am running the dx9 version of the game...

UPDATE:
I've been able to narrow down the area of issue significantly through some testing... I can't say these results are 100% conclusive, but pretty close... I 'turned off' the G&K DLC, and started a new game (with the mod still) - The only 'error' that remained was that the leader/diplo screens weren't animated. EVERYTHING else worked fine, didn't crash at all. I also tested the game with the DLC 'on' but with NO mods active - The game worked perfectly (even the leader/diplo screen). This makes it is quite obviously something to do with the interaction between the G&G DLC and the Mod.
I have, with my saved game (both G&K and Mod running), run into a repeatable crash trigger as well. Basically, as soon as I load up my latest save, I have a 'pop-up' telling me that i can "purchase with faith", but when I try to open the 'purchase' list in *any* city screen, the game crashes immediately. This is more iffy than the above tests, but it does *suggest* that (at least one of) the crash trigger is due to a conflict between the faith/religion mechanic of G&K and RED (the mod).
I will follow this up later, testing weather the 'faith purchase' crash prevents me from ending the turn, and if it persist into following turns. This will hopefully pin down whether the crash is *directly* linked to the faith mechanic, or if that connection is coincidental and the cause is actually different...
