kde 4.2.90 apps crashing with No module named qt

[Jithin Emmanuel]

In my xsession errors I can see these

kdeinit4: preparing to launch /usr/lib/libkdeinit4_korgac.so
Could not open library /usr/bin/korgac: Cannot load library /usr/lib/libkdeinit4_korgac.so: (/usr/lib/libkdeinit4_korgac.so: cannot open shared object file: No such file or directory)

I believe package python-kde4 is not available for kde 4.2.90.

I installed via kubuntu-backports PPA
