# Removing bullets in headline with own template doesn't work

I'm using Ilmenau in a beamer presentation (first image)

I want to hide the bullets, so I use my own headline template (I get the idea from Is it possible to get rid of the bullets in the miniframes outer theme ). I remove the bullets but I get a white box on top of the slide instead (second image). I want to remove the bullets and the rest of the header elements move to the top.

I'm using this code:

\usetheme{Ilmenau}

{%
\end{beamercolorbox}
}


UPDATE: Complete snippet: The empty template output white space on top, but if you uncomment the headline template body, is more strange even.

Move the redefinition for headline to the preamble:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{lmodern}
\usepackage{listings}
\usepackage{graphicx}

\title{Active Galactic Nuclei}
\author{John Doe}
\usetheme{Ilmenau}
\usecolortheme[rgb={0,0.4,0}]{structure}

\setbeamercovered{transparent=20}
\newcommand*\oldmacro{}%
\let\oldmacro\insertshorttitle%
\renewcommand*\insertshorttitle{%
\oldmacro\hfill%

{%
\end{beamercolorbox}%
}

\begin{document}
