One of our users uploaded an animated gif file for his avatar. The fisheye.out and fisheye-error.log files had 133 lines of error messages every 10 seconds until he installed a non-animated file 6 hours later. When I noticed this the log files were over 6 MG. Had he not installed a good file the log files would have continued to grow and eventually could fill a system.

Documentation should include a notice to NOT use an animated image. Some type of alert to the user or administrator would be good. Email notification or something to inform the user and/or admin that there is a problem.
