YOU Upodated and now mega HTML errors

Hi, I did a YOU today and it helpfully made some changes to Mozilla and some other files. Now when I try to load a page - any page - in Konqueror I get the following: There was an error loading the module KHTML. The diagnostics is: /opt/kde3/lib/libkdeprint.so.4: undefined symbol: addColumn__9KListViewRC7QStringi And then: There was an error loading the module KMOZILLA. The diagnostics is: /opt/kde3/lib/libkdeprint.so.4: undefined symbol: addColumn__9KListViewRC7QStringi and then Could not create view for text/html The diagnostics is: /opt/kde3/lib/libkdeprint.so.4: undefined symbol: addColumn__9KListViewRC7QStringi Any ideas anyone? Thanks in advance, Nick
