iOS crash after saving story

On the NewsBlur iOS app - when I go through all of my saved stories and unsave them (via the slide action saved stories screen) and then go back to the main screen the app crashes.

  1. Save a story
  2. Mark that story or group as read
  3. Go to the saved stories
  4. Unsave that story by sliding it to the right
  5. Go back to the main screen
  6. App crahes

It also crashes when you try to add a saved story tag.
