For clarification: Did this happen the first time after you initialised the client/ deleted its database? Or after you restarted it without having written someone or having recieved messages before ? Because my guess is that the Client tries to sort the List with all the messages from the database and throws a NullPointerException because there are no messages in the list.

Wasn't able to reproduce error, there issue is put on hold until someone else recieves this error again.
