Recruit
So if you have sworn to not attack a faction, in exchange for them leaving you alone, and then you and an army of the faction you have sworn not to attack ends up on the opposing side of a siege, then when the assault begins, it won't let you click "Fight!" because "you have sworn not to attack" and you can't "send troops." for the same reason. and since there is no option to run for the hills, then you can't get beyond the screen and is thus stuck and have successfully soft-locked yourself.
