Fedora 12 Update Breaks X / KDE

[Chris Ross]

Yesterday I did a normal yum upgrade and it pulled in a few packages 
(listed below).

Since then I've had problems such as Kate refusing to run, with

kate: symbol lookup error: /usr/lib/kde4/katepart.so: undefined symbol: 
_ZN9QGroupBoxC1EP7QWidget

Konsole taking several attempts to start up without segfaulting

Acrobat Reader immediately crashes the X server on startup

and more. Does anyone else see this? Know when another yum upgrade will 
fix it?

The packages that got updated were
