Lots of changes to anaconda in the past day or so to get rid of our use of deprecated bits of GTK+ (GtkCombo and GtkOptionMenu). Since pygtk warns about these and people file bugs if I leave the warnings in, I went ahead and fixed things in advance of that.
This, of course, means that some reasonable testing is needed of the changes. So if anyone is interested in doing so, basically just poke around a lot on the partitioning screen trying as many different setups as you can think of (you don't even have to go on and destroy your partition table, you can just play around for a while).
Should show up in Fedora devel tomorrow, any problems noticed should get filed in bugzilla and I'll fix them up.
