Synaptic relocation error

I'm using 9.0. I used Yast to upgrade the kernel to 2.4.21-226-athlon and now I can't open synaptic: :~> sudo /usr/sbin/synaptic Password: /usr/sbin/synaptic: relocation error: /opt/gnome/lib/libgtk-x11-2.0.so.0: undefined symbol: g_type_class_add_private I reinstalled synaptic but the problem persists. How do I solve it? Thanks, Jerome
