I use drupal whith "locale" for French.
In public download report page, all links are added with a non existant "fr" directory. So they link to nothing.

For example "detail" link in "operation" column link to http://mysite.com/fr/admin/reports/pubdlcnt/counter/Jerome.epub
But the real link is : http://mysite.com/admin/reports/pubdlcnt/counter/Jerome.epub
whithout the /fr/

I think this the same issue than this one : http://www.pixture.com/drupal/node/161#comment-1823
This caused by adding /cs/ for Czech Republic.

Thanks for this very usefull module.
