Actually, more like -> 8.5.0.1 as this version is made against the
branch with the pending fixup patch applied.

(cherry picked from commit c4962cd)

If dropbox can't load libappindicator, it will fallback to using the old
xembed protocol. If you (or your Desktop Environment) are running
something like KDE's XEmbed SNI Proxy, then you'll at least see an icon,
but clicking the icon won't give you menu.

Adding libappindicator to the env allows dropbox to fully integrate with
contemporary status trays, while still falling back to xembed if the
required DBus service is not present.
