Maybe an issue with the web server?
Downloading the file with firefox and wget will give different files:
216856 May 30 11:38 firefox/comps-sl6-x86_64.xml.gz
216991 Mar 22 19:10 wget/comps-sl6-x86_64.xml.gz
The Apache is zipping the file on the fly again, but firefox does not
unzip it right:
firefox/comps-sl6-x86_64.xml: gzip compressed data, from Unix, max
compression
firefox/comps-sl6-x86_64.xml.gz: gzip compressed data, from Unix
wget/comps-sl6-x86_64.xml: XML document text
wget/comps-sl6-x86_64.xml.gz: gzip compressed data, from Unix, max
compression
firefox/comps-sl6-x86_64.xml is the original zipped file!
Sniffing while downloading with firefox:

I think apache should be configured not to zip already zipped files.
