Okay...so we're pretty sure that some change made between the June 3 and August 15th beta patches is causing a sudden increase in the instances of CTDs but both Byakhiam and I have been through the changes and can't see anything obvious. It's possible that the reason is simply that we're so familiar with the files that we simply don't notice the error and that a "fresh" set of eyes will spot something that we won't...so here's your chance to be a bug detective! 
Attached is a rar file. Download it and unpack it TO A NEW FOLDER (not to your CK game folder).
You will then see a list of html files that you can click on to open in whatever your default browser happens to be. This is a comparison report of all changes made to all database and event files between the two patches. The June 3rd version is shown on the left and the Aug 15th version is shown on the right. Changes are highlighted, and a few lines of "context" are shown around each change. You will also see the line number of the file if you want to go to the file and look up the entire event yourself.
If anyone can spot an error in there, please post back the details here.
If we can't find any errors then I guess we'll move on to the scenario and character-related files in case there's something in there that's causing the crashes, but with the majority of your crash reports ending with a rpvince_effect call, the most probable bug will be in an event that is changing province effect.
Good luck, and happy bug hunting.
