The French ability to double building-boni on Worldwonders works fine as long as you have just one bonus. When you get several boni (e.g for social politic, religion and marmor stone) at the same time it happens, that boni are getting lost (like marmor bonus in the picture) - and not all boni are getting doubled. I took a screenshot as you can see.
As long as only one bonus can be doubled at all, Egypt would always be the better choice than France. Please solve that bug :)
