I suggest changing Settings.txt so that rioting planets produce at 25% instead of 0%. While it may be realistic that all factories shut down during riots, it makes for very, very not fun games when most of you empire riots at once due to an invasion, so you can not possible mount any sort of defense effort. 25% still gives a big penalty for rioting, but it at least allows you to do something in such situations.
