Bug#1079490: caja-dropbox: please don't depend on dbus-x11

[Simon McVittie <smcv@debian.org>]

Package: caja-dropbox
Severity: normal
User: dbus@packages.debian.org
Usertags: dbus-launch

caja-dropbox has a dependency on the dbus-x11 package, which seems to
have been added at the same time as a patch (subsequently removed) that
ran it wrapped by dbus-launch for some reason.

The dbus-x11 package is unnecessary on typical Debian desktop systems
which have systemd and dbus-user-session installed, and it has some
backwards-compatibility side-effects which are not ideal, so I'm trying to
reduce direct dependencies on it.

If caja-dropbox needs a D-Bus session bus, the correct dependency is:

    default-dbus-session-bus | dbus-session-bus

which in practice can be satisfied by either dbus-user-session or dbus-x11.
Or, if it doesn't actually need a D-Bus session bus, then the dbus-x11
dependency is unnecessary and can be dropped.

Thanks,
