Issue

This problem occurs when replying or forwarding emails.  You type up an email, click send, and the recipient replies back saying that you sent them a blank email!

Explanation

This problem occurs because of a Javascript error caused by a mal-formatted Default Font Color setting in your Email Settings.

Workaround

Check the Default Font Color setting in your Mail setting, go to Settings > Mail, and select a new color from the color picker to the right of the box or enter the hexidecimal equivalent preceded by a # (#000000) for Font Color.  Apply your changes, and the emails you compose should be received normally..
