This should only be the case for the matched gzip_types, though not *all*
uncompressed responses. Have you included (inappropriate for compression)
image and audio types in gzip_types? If so, remove them, and you should be
done (unless there is a bug in nginx -> but I haven't seen a similar thing
happen on my servers).
