The test in question (test/test_webrobots.rb context "robots.txt in the real world" do should "be parsed for major sites" do) apparently needs a working internet connections and the tested sites in question need to be up (and not change their configuration).
I suggest disabling this test, at least during build time. -ch -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
