I looked into it just for interest's sake, and here's my observations:

Qt4 web browser launch code:
===
static bool launchWebBrowser(const QUrl &url)
{
    if (!url.isValid())
        return false;
    if (url.scheme() == "mailto")
        return openDocument(url);

    if (launch(url, "xdg-open"))
        return true;
    if (launch(url, getenv("DEFAULT_BROWSER")))
        return true;
    if (launch(url, getenv("BROWSER")))
        return true;

    if (X11->desktopEnvironment == DE_GNOME && launch(url, "gnome-open")) {
        return true;
    } else {
        if (X11->desktopEnvironment == DE_KDE && launch(url, "kfmclient 
openURL"))
            return true;
    }

    if (launch(url, "firefox"))
        return true;
    if (launch(url, "mozilla"))
        return true;
    if (launch(url, "netscape"))
        return true;
    if (launch(url, "opera"))
        return true;
    return false;
}

On Mandriva 2007.0, xdg-open doesn't exist, but BROWSER is set 
to /usr/bin/www-browser. www-browser is a shell script that will load the 
browser that was set by the active desktop environment. If a browser isn't 
set by the DE, then Firefox is the first browser to be launched by default.

So, I'm guessing that my problem is that KDE launches Konqueror if a browser 
isn't explicitly set for it, while www-browser launches Firefox. I suppose it 
could be considered that there's a bug with the script since the launching 
behaviour is inconsistent.

Doesn't explain your problem though, Hal. ;)
