I am indeed using Safari.

This is ironic since, of all the popular desktop operating systems,
Mac OS X is the one that doesn't have to rely on extension to
determine the file type.

It's not a bug though. The MIME type says it's a tar file so Safari
applies the tar extension. You can argue that correct behaviour is
not to change the file name at all (I probably would), but not that
something that claims to be a tar file should be flagged as a gzip file.
