This bug is caused by the recent package split of libgconf2-4 into
libgconf-2-4 and gconf-service.  This upgrade includes a Breaks: on the
old version of libgconf2-4 by libgconf-2-4, which ensures that
libgconf2-4 is deconfigured before libgconf-2-4 is unpacked on upgrade.
However, this does *not* ensure that gconf2 is deconfigured when the new
libgconf-2-4 or libgconf2-4 is unpacked, so its trigger may still fire,
even though the files it relies on are either no longer on disk (if
libgconf2-4 has been unpacked without libgconf-2-4) or not where they're
expected (if libgconf-2-4 is unpacked without gconf-service).

We need to ensure that the gconf2 trigger is *only* called under the
following circumstances:

 * new libgconf2-4 not yet unpacked, new libgconf-2-4 not yet unpacked
 * new libgconf-2-4 unpacked, new gconf-service unpacked

To achieve this, we can have the new libgconf-2-4 and libgconf2-4
packages both declare a Breaks on the old gconf2 version.  This forces
gconf2 to be deconfigured when either of these new packages is unpacked,
and remain deconfigured until both libgconf-2-4 and gconf-service are
configured (since gconf2 already has a dependency on both of them).
