If you find a naturally occurring village in the later snapshots, you'll find there are absolutely no farmer villagers. As well as this too many clerics and librarians will spawn (even if there are no churches/libraries). Blacksmiths/butchers will spawn normally, in other words, if there is a blacksmith shop/butcher house, there will be a blacksmith/butcher.
THIS ONLY AFFECTS DESERT VILLAGES, regular villages seem unaffected by this? <---(another possibility is that it only affects villages which have a blacksmith shop/do not have a butcher shop)

MC-45571 is completely different, it applies to super flat and claims to be fixed in 14w07a, this issue is still present in 14w08a and occurs in all instances of villages with not yet clear exceptions, it also affects spawn rates of other villagers like clerics and librarians
I suggest you to use the search function and turn off caps in certain parts of your reports.
