Konqeror failure

After trying mozilla as my default web browser, I tried to go back to Konqueror. I went to Control Center->KDE Components->File Associations and moved Konq back to the top of the list. Now, when I call up Konq and try to go to a website, I get the following error message: There appears to be a configuration error. You have associated Konqueror with text/html, but it can't handle this file type My first thought was to reinstall it, but apparently it's so deeply embedded in KDE that this isn't an option (not even listed in Yast2). Does anyone have an idea what might be wrong and how to fix?
