    //           is not set
    //        2) it doesn't look into ~/.kde/share/config/kdeglobals where
    //           user's settings are stored and thus *ignores* user's settings
    //           instead of respecting them
    //        3) it "tries to guess KDEDIR" and "tries a few likely theme
    //           names", both of which is completely arbitrary; instead, the
    //           code should give up if KDEDIR(S) is not set and/or the icon
