Are you able to reproduce this one in eolie, or was it random?
My guess is that there aren't any dictionaries in the system and m_enchantDictionaries contains a single element that is nullptr, because enchant_broker_request_dict() can return NULL and we ar enot checking it.

There are dictionnaries on the system but enchant_broker_request_dict() may have return null.
