Ribbit - Selecting a message in the inbox throws an exception.

It seems as though the identifier showImage is giving me some trouble - does anybody have an idea as to why?

Done.

Small mistake. You had created your segue from the Navigation controller instead of Table View Controller. It is fixed, tested and... it works!

I sent you a pull request. Take a look at it in GH.

On your Storyboard click on the segues out of your InboxTableViewController and check if all of them have identifiers.

They sure do, double checked for typo's as well.

Put the project somewhere (github?) and I promise I will take a look at it.
