I've tried with .csv and .xlsx files from email. I've had a couple of users of my app report the same. pic.twitter.com/Jg7wD8PQyq

Steps to Reproduce:
1. Open the Mail App in iOS
2. Open an email that has an .xlsx file attached to it
3. Download the file
4. While viewing the file, select the share option in the upper right
5. From the share sheet, scroll through the apps and select "More"

Result: The Mail App for iOS crashes if the user downloads either a .csv or an .xlsx file and then selects "More" from the sharesheet

Expected: The Mail App for iOS should not crash after the user downloads either a .csv for an .xlsx file and then selects "More" from the sharesheet menu

Download an .xlsx file from an email message...

Select the share option...

From the Share Sheet, scroll the icons over to reach "More"...

Selecting the "More" option crashes the iOS Mail app.
