However clicking on the 'Download' link produces a blank window in Phoenix (yes, my browser is that old), wget http://cvs.livejournal.org/browse.cgi/~checkout~/livejournal/src/jbackup/jbackup.pl?rev=1.1&content-type=text/plain produces a 500 Internal Server error..
I would have reported this as a bug in Zilla, however the Zilla page isn't linked on livejournal.org (and here is) and I'm that lazy ;)
