This one is very strange. First is the error in test_image_usage_in_redirects , then one of the results in test_image_usage_no_redirect_filter is wrong!

Another error in test_image_usage_no_redirect_filter

(It is probably not the same bug as the test_image_usage_in_redirect bug, and a new bug should be created once we have more information about the cause.)
