On some devices Neocom can crash on switching characters.
Application crashes on updating new mails. It happens only if fetching recipient names fails with error (NSError object released twice). Indeed it occurs very rarely on some accounts. You can temporary disable mail and notifications access for your API Keys (https://support.eveonline.com/api). You will be unable to read mail, but application will no longer crash. I already fixed this bug, but Apple require a week to review.
