I've had this problem happen repeatedly to myself and my team. There is also a bug where the "Party leader quit" notification at the bottom of the screen stays while not in game. So from end of match lobby to ready up lobby and then all the way to character select it remained. The only thing that helped was to restart the game.
This is a pretty bad bug, it makes the people that I just got interested in playing with me...bail.
I never had this issue until tonight. One of my squadmates had this issue once or twice where it did not kick him, I have been kicked by this issue 4 times in 3 hours randomly. Seems to occur, for me, after I have been AFK, got the in-game "You have been kicked due to inactivity" message, and clicked the "Continue" button without restarting the game/Origin client.
