After enabling Menu Translation and going to admin/build/menu/menutranslation, I get a warning message that says "Please select a menu that you want to translate in the menutranslation settings." The message attempts to link to menutranslation settings, but it links to it from the htdocs root rather than the Drupal installation base directory. So, instead of linking to drupal/admin/settings/menutranslation, it links to /admin/settings/menutranslation, which of course is a dead link since Drupal is installed in /drupal on the web server.
