Description: The user opens an image in gallery, taps the share icon, and selects email. If there is no email account set up on the device, they are brought to the "New Account" page, and prompted to add an email. The user taps the back arrow to return to gallery, and attempts to share via email again. This time they are brought to a blank page with no back arrow. They can press the home button to escape, but if they go back into gallery and tap the share icon it will be unresponsive. From here, if they select the email icon from the home screen they are brought to same blank page. If they close email via card view, gallery and email begin functioning normally again. Repro Steps: 1) Update a Aries to 20150710105517 2) Ensure that no email account is set up on the phone, and there is at least one picture in gallery. 3) Go to gallery, tap the share icon, and select email. 4) On the "New Account" page, tap the back arrow to return to gallery. 5) Open the image, tap the share icon, and select email. Actual: User is taken to a blank page, and sharing from gallery will not be functional until the email app is manually closed. Expected: User is taken to the same "New Account" page as when they first attempted to share.

If they back out and try to share again they get the same pop-up. If the pop-up is confirmed, they are brought to the "New Account" screen, and if they back out of that screen and share again, they are brought to the "New Account" screen again with no issue.
