Just getting no response from kde apps such as konqueror or dolphin. So I tried starting from a terminal. I have posted the terminal contents:

> dolphin
dolphin: symbol lookup error: dolphin: undefined symbol: _ZN19KonqFileUndoManager6incRefEv
<unknown program name>(3886)/: Communication problem with "dolphin" , it probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "


> konqueror
konqueror: symbol lookup error: /usr/lib64/libkdeinit4_konqueror.so: undefined symbol: _ZN19KonqFileUndoManager6incRefEv


I notice a common part to both:
ZN19KonqFileUndoManager6incRefEv

This is a bit out of my depth. Anyone!

KDE 3 is fine
