Synaptic quitting

Some applications like k3b and the updates of KDE to KDE 3.1.95, the alsa and gstreamer updates cause synaptic to quit with this message: :~> sudo /usr/sbin/synaptic Password: (synaptic:2656): Gtk-CRITICAL **: file gtkwidget.c: line 1827 (gtk_widget_hide): assertion `GTK_IS_WIDGET (widget)' failed /usr/sbin/synaptic: relocation error: /usr/sbin/synaptic: undefined symbol: _ZN15pkgVersionMatchC1ESsNS_9MatchTypeEi adriel@Cosmos3:~> sudo /usr/sbin/synaptic Anyone know what's happening here?
