Just downgraded to glib2 2.12 because of all the g_thread_init problems reported
in many other tickets, and now gtk2 reports an undefined symbol g_sequence_new.
It appears that gtk2 in devel depends on glib2 >= 2.13, but the dependency in
the rpm says >= 2.12.0-1. This needs to be fixed.
Fixed in 2.11.3-4.fc8
