Object has no attribute 'name_None'

Toen ik !246 (merged) aan het testen was kreeg ik opeens de onderstaande foutmelding. Het gekke: ik kreeg m niet nog een keer. Het leek me goed om m hier te posten.

Het doet me denken aan de exception die @jvrancken(?) en ik tegenkwamen binnen events, waarna ik translation.py aanpastte om dit te voorkomen en toen was niets meer vertaald. Dat is teruggedraaid, dus misschien is het dezelfde issue? Probleem is dus dat ik m nu niet nog een keer kreeg.
