I have the same error, at least a dozen times. I never took a screenshot of it (Never thought to, sorry!), and the only way out temporarily was to go into the Dev console and 'destroy' the faction visitor that is causing said error.
The error is only shown through the log, and the game also pauses indefinitely until I remove my faction allies permanently from the game. =(
Here is all the mods I have enabled for Rimworld v13: http://imgur.com/8H73I5z
As for how it happens, it seems as though every-time a faction's pawns have high enough of a relationship with my colony- they attempt to join. It then stops the game with the afore-posted error by the user above you. So far I have been unable to recruit from factions as a result.
(Update---> Here is another log of the similar error that pauses the game: http://imgur.com/ebMcyme )
