<p>For objects that discover their interfaces at runtime, this method will
indicate that interfaces are missing until they are known to be present.
In subclasses that define features for use with <a class="link" href="telepathy-glib-proxy.html#tp-proxy-prepare-async" title="tp_proxy_prepare_async ()"><code class="function">tp_proxy_prepare_async()</code></a>,
successfully preparing the "core" feature for that subclass (such as

<p>Emitted when this proxy has been become invalid for
whatever reason. Any more specific signal should be emitted first.</p>
<p>An invalidated proxy is one which can make no more method calls and will
emit no more D-Bus signals. This is typically because the D-Bus object
represented by the proxy ceased to exist, or there was some error
obtaining the initial state.</p>
<p>Any pending or future method calls made on this proxy will fail gracefully
with the same error as returned by <a class="link" href="telepathy-glib-proxy.html#tp-proxy-get-invalidated" title="tp_proxy_get_invalidated ()"><code class="function">tp_proxy_get_invalidated()</code></a>.</p>
