Does this happen a lot?
If you try to reload the page, does Konqueror show it, or does the proces protocoll die again?
Figuring out what went wrong with the installation of KDe is indeed difficult.
A workaround is using another browser, like Opera, Mozilla, or Galeon.
to use them as default in KDE, go in kcontrol to kde components -> File asociation, select the mime type for html, and add your favorite browser, like Galeon %U. some browsers expect a flag (like %U), others don't. U can check that out by running browsercommand --help[b/] from the commandline.
