changelog is never available in 12.04

[Marius Gedminas]

Ever since I upgraded to 12.04, I've been unable to see package changelogs in the Update Manager window. It always says: "Pakeitimų žurnalas dar neprieinamas.", which is Lithuanian for "Change log not available yet."

There's a launchpad link with the changelog that works fine, which makes me wonder why update-manager is incapable of using it by itself.
