If you install kde dependent programs, such as k3b or kile, and you have not
recompile them with the kde3.4 library, deleting /usr/kde/3.3 will
certainly break library dependency of the programs.

I suggest you doing this,

1. delete /usr/kde/3.3 directory (or rename it to some thing else if you not
sure)
2. run "revdep-rebuild -p", this program will show any packages that have
broken library dependency. You can decide to recompile the package with
new library, or re-install the library itself.

Have fun,
Tom
