   Hello.   
      
   Using current 64 with xfce4, when I open a pdf with okular,   
   it opens flawlessly, but on the terminal I get the   
   message:   
      
   Icon theme "gnome" not found.   
   Icon theme "crystalsvg" not found.   
      
   Installed every theme* from SBo.   
      
   But now, since an upgrade,   
   when I open the pdf and close it, above message appears.   
   BUT when I inside okular start presentation mode (STRG+SHIFT+P),   
   this comes up (command line):   
      
   org.kde.okular.ui: Unable to inhibit screensaver   
   QDBusError("org.freedesktop.DBus.Error.ServiceUnknown", "The name   
   org.freedesktop.ScreenSaver was not provided by any .service files")   
      
   Killed xfce-screensaver, which didn't work anyway, same message.   
      
   xpdf triggers no error message, but it seems to have no presentation mode.   
   gv : no error message.   
      
   I guess I configured something badly.   
   But, above all, I'd like to understand.   
      
   What has okular to do with screensaver?   
   Why did this message come up after an upgrade   
   (sadly I don't remember which)?   
      
   cheers Erich
