fast/images/slower-decoding-than-animation-image.html

This test has been failing for all visible history. 

I was able to reproduce the failing by running it in iterations. Here is the command I used: 'run-webkit-tests --root debug-256764 fast/images/slower-decoding-than-animation-image.html -1 -f --iterations 5000 --debug' and it failed 32 times.
