Use g_signal_connect_object to connect the embed signals, that way they're

2004-01-17  Christian Persch  <chpe@cvs.gnome.org>

	* embed/mozilla/mozilla-embed.cpp:
	* src/ephy-tab.c: (ephy_tab_init):

	Use g_signal_connect_object to connect the embed signals,
	that way they're disconnected before the tab object is
	finalised. Should fix crasher bug #131635.
