Images not displaying in question previews

If you create a question in the question bank and put an image in the question text the image will not display correctly when you preview the question. It works fine in the editor but not in the preview window.

I visited the image URL directly and the following error is displayed.

Coding error detected, it must be fixed by a programmer: PHP catchable fatal error
