When you say "is killed", are you sure you don't mean "fails an
assertion and aborts"?

You're not allowed to call just about any API on a dbus-glib DBusGProxy
after it has emitted the "destroy" signal. If you do, it'll fail an assertion
and abort the calling process. To fix this, use g_signal_connect to listen for
the "destroy" signal, and when it's emitted, stop using the proxy.

Hope this helps,
