KDE4init broken after security update

Upon boot up yesterday I found 3 security updates which I applied with no errors. When I next re-booted I got an error stating the KDEinit could not be started and to check my installation. Is there an apt command to restore KDE?

Follow Up:

Actual error:
usr/lib64/libQTGUI.so.4: undefined symbol: _ZNK (bunch of characters)
Startkde: could not start kdeinit4. check your installation

How can I fix this?

LibQT update today fixed the problem
