Roman pagenumbering + \usepackage[greek]{babel}

Roman pagenumbering + \usepackage[greek]{babel}

I have the problem that the roman or Roman pagenumbering does not work if
babel is used with greek option. Does not work means, that the pages
itself have correct numbers but the table of contents will show only the
number the toc is on. Any suggestions what might help?
In case you want to proof yourself:
\documentclass[listof=totoc]{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage[greek, ngerman, english]{babel}
\usepackage{blindtext}
\begin{document}
\pagenumbering{Roman}
\addchap[Preface]{Preface}
\blindtext
\addchap[Thank You]{Thank You}
\blindtext
\tableofcontents
\listoffigures
\listoftables
\cleardoublepage
\pagenumbering{arabic}
\chapter{Test}
\blindtext
\end{document}
