Perhaps try this:

export EAS_DEBUG=5 SYNCEVOLUTION_DEBUG=1
./dbus-session.sh /usr/libexec/activesyncd syncevolution --daemon=no
--print-databases username=$email backend=eas-events

That's a bit simpler because SyncEvolution doesn't try to move execution into
syncevo-dbus-server. That should work, but who knows.

Auto-launching activesyncd seems to work. No idea why there is no further
output.
