Some issue with wget's compression detection?

$ LANG=C wget http://zim-wiki.org/downloads/zim-0.67.tar.gz -O zim-0.67.tar.gz ; md5sum zim-0.67.tar.gz ; rm -f zim-0.67.tar.gz

With '--compression=none' the md5sum matches what's on SBo:

$ LANG=C wget --compression=none http://zim-wiki.org/downloads/zim-0.67.tar.gz -O zim-0.67.tar.gz ; md5sum zim-0.67.tar.gz ; rm -f zim-0.67.tar.gz
