In case of colliding usernames found during converting from phpBB 2.0.x, PHP error is thrown in /install/convertors/functions_phpbb20.php around lines 1905 (3.2.11) / 1879 (3.3.10).
The cause is missing COLLIDING_USERNAMES_FOUND language variable which was probably lost during installer refactoring.
