[Bug 488861] Re: [Kubuntu Karmic/9.10] Clicking on "Multimedia" in KDE 4.3.3 "System Settings" results in symbol lookup error

[Gustaw Smolarczyk]

I think the problem is Qt 4.6 which lack needed symbol (nb. qt 4.6 is in lucid only for now, not karmic...). Try this simple hack I hope won't break Your system :)
As superuser:
# cd /usr/lib
# mv libQtCore.so.4.6.0 libQtCore-o.so

Then paste attached replacement for libQtCore.so.4.6.0. And now a tricky
thing: open libQtCore-o.so with okteta, find "libQtCore.so.4" string and
change it to "libQtCore-o.so" <- this will (hopefully) change soname. If
you don't want to run okteta as superuser, copy this file to your home,
make change and then as superuser copy it back to /usr/lib.

This solution is very tricky and could break things, but I used it on my system and everything seems to work ok.
The simpliest way to repair this is to downgrade to Qt 4.5 and KDE 4.3.2 from Karmic.
