KDE-Forum.org

I use fedora core1+kde 3.1.4-6 (using kde 3.1.4-4 Red Hat)

I am not sure to have modify any preferences in konqueror but when I lauch konq I get automatically three times this particular error messages :

"There was an error loading the module KHTML.
The diagnostics is:
/usr/lib/libkdeprint.so.4: undefined symbol: _ZN7KTrader4selfEv
_ZN17QValueListPrivateI10KSharedPtrI8KServiceEED1Ev"

after the validation "ok" 3 times I can only use konq to see the files directory but I can't surf the net.
the same error exist under another user and with kde and gnome envirmt-

I need help, thanks
