Comment 21 for bug 1034668

  Installing libdbusmenu-glib1 as Depends of indicator-me
[...]
Broken indicator-appmenu:amd64 Conflicts on libdbusmenu-glib1 [ amd64 ] < 0.2.9-0ubuntu3.1 > ( libs ) (< 0.3.7)
  Considering libdbusmenu-glib1:amd64 9 as a solution to indicator-appmenu:amd64 3
  Holding Back indicator-appmenu:amd64 rather than change libdbusmenu-glib1:amd64

So this is triggered by the obsolete indicator-me package. indicator-messages already conflicts with indicator-me, but the conflict is applied too late in the upgrade.

Aside from libraries, this is the only reverse dependency of libdbusmenu-glib1 in lucid that does not have a version available for upgrade in precise; so chances are that adding a conflict against indicator-me will be sufficient to get this upgrade to go through correctly. If it *doesn't*, then we should deal with this via an update-manager PostDistUpgradeCache quirk instead to force upgrade of indicator-appmenu instead of continuing to hack around it with conflicts.
