Email application not displaying message bodies

Below is a picture of the problem one of my users is having on their VZW Motorola Droid RAZR running ICS. The picture (click to enlarge) is a screenshot of the default email application configured to sync Yahoo Mail over IMAP. The white border in the bottom of the picture is where emails are normally displayed. There does not seem to be any determinant in which emails present this problem. Does any one know why this issue might present, and how to fix it? [](https://i.sstatic.net/CS0Z3.png)
