Description:

I keep getting the same crash with the current version of the iMovie app for iPhone. 

This crash keeps occurring for me while I am editing a movie on the "My Movie" edit screen. 

Here's a video of the crash:

Steps to Reproduce:

1. Open iMovie

2. Start a new New Movie project

3. Select "Movie" 

4. Select any video "Recently Added" - Select "Create Movie"

5. Scroll to the start of the film and select the "T" for text

6. From the text options, scroll to the right and select LINE/TITLE

7. Select the top "TITLE TEXT HERE" option and select "Edit"

8. Exit out of iMovie by pressing home twice

9. Copy text out of Facebook Messenger

10. Select the bottom "Title Text Here" and select "Edit"

Result: the iMovie app for iOS keeps crashing for me after I try to edit the bottom line of the "LINE/TITLE" text option - crash seems to happen after I exit out of app, copy text from FB Messenger, and then return into the app to Paste the text

Expected: No crash!

Here's the crash dump.
