On mediawiki go to any Flow-based page. Even on an empty board, the loading the page produces "Uncaught TypeError: Cannot read property 'trim' of undefined".
The Flow page is completely broken - no editing is possible.
Note: The error appears about a week ago in betalabs, but it did not affect Flow's functionality.
