Just push it. It fixes the issue. We can look into av_print_format()
or other such subtleties later on. They're mostly cosmetic (they give
cute warnings when using a wrong format string/arguments combination),
whereas your current patch fixes a real bug, possibly exploitable
(depending on the use of snprintf() by the caller).
