I think the only viable way is logging out and in of your desktop session,
really. We could add a way to have (say) MC tell all your CMs and clients to
die/reload themselves … and some clients like Gnome Shell can restart itself
without losing too much state, but the user might be a bit annoyed if they
upgrade Telepathy and AbiWord (say) commits seppuku in sympathy.

So I don't think it's entirely obvious how to solve this—but note that it's not
entirely a new problem, as we already have issues with MC not noticing new CMs
(bug 30210 and bug 24511). Definitely separate bug territory, and maybe should
only strike end-users on distro version upgrades, which we can assume will
involve logging out and in (or maybe a reboot)?
