Aha. We should start being better about keeping the PPA in shape for
Maverick, then. I've just gone through and copied lucid versions of
pocket-lint, bzr-lpreview-body and launchpad-dependencies (!) to
maverick and karmic. Everyone, please remember when you upload to the
PPA to take care of all active distroseries, if you can.

Also, I note there's a bzr-pqm package for lucid in the PPA - a recipe
build(?) by matsubara. Could someone scribble something on
https://dev.launchpad.net/LaunchpadPpa about why it's there, so we know
whether we need an equivalent for maverick? (And in theory, karmic and
hardy).

This can also be caused by pinning using apt preferences.
