We're drifting off topic for this issue (which is supposed to be about
D-Bus rather than Jami on foreign distributions :-)), but for the sake
of completion, the following works (tested on a Debian 10 i386 VM):

$ guix environment --ad-hoc jami-gnome dbus glib gtk+ openssl nss-certs \
  -- dbus-run-session jami-gnome

Apparently the FileChooser schema is provided by gtk+.  I also found out
that OpenSSL from Guix wants the SSL_* environment variable sets, so I
added the nss-certs and openssl packages to the mix (otherwise you
wouldn't have been able to search for contacts).

I think for gtk+/glib this can be improved by adding the
glib-or-gtk-build-system phases to the jami-gnome package definition.

HTH!
