[packagekit] pk-update-icon segfaults

[Scott Reeves]

I am running slightly newer git than 0.1.7.  This happens with both the zypp backend and the dummy backend.

The segfault occurs in pk_client_finished_cb.  The method is initially entered with a valid PkClient reference but in this method it does a g_signal_emit of PK_CLIENT_FINISHED.  There appears to be a reference count problem or something because this appears to free the PkClient reference such that when the signal emission returns the PkClient reference is no longer valid and the client->priv->synchronous access causes a segfault.

I have attached the backtrace.
