After William Brewster joins the congress, when an emigrant selection is made the game freezes and doesn't continue.
I am attaching FreeCol.log, screenshots and the save game. To reproduce hit "end of turn" and select any of the emigrants when the selection appears.
FreeCol.log file. I end the game by hitting Ctrl-C in the shell I run the game.

The save game itself. To reproduce the error, hit end of turn and make an emigrant selection.
