So you installed KDE4 on Elyssa KDE?
It's supposed to use KDE 3...
I fear this is unavoidable - it's likely these are different versions

You likely have a full set of KDE4 apps installed with KDE4, and since you claim you have "duplicates" then it is likely you installed KDE4 on top of the KDE3.5.9 that came with the Mint KDE CE distro. So now you have duplicate KDE apps, some KDE3 and some KDE4.
