[Tex/LaTex] Section title doesn’t fit in TOC in beamer

Question

So I have a section in my presentation with a longer name. And on the slides I just used \small, and it fit onto the slide, but on the toc it doesn't 'break', it just continues on cutting off the title of the section :
Is there a way to make it fit, or to continue underneath the section?

MWE:

\documentclass[xcolor=dvipsnames,mathserif,professionalfont,12pt]{beamer} 
\usecolortheme[named=RoyalBlue]{structure} 
\useoutertheme{infolines} 
\usetheme[height=7mm]{Rochester} 
\setbeamertemplate{items}[ball] 
\setbeamertemplate{blocks}[rounded][shadow=true] 
\setbeamertemplate{navigation symbols}{}
%\usefonttheme{serif}
\usefonttheme{professionalfonts}

\subsection{A very long subsection that doesn't want to collapse into two row, but rather goes on and on and on}

EDIT: This is the output:

Compiling with latex-ps-pdf hyperref isn't able to break links directly. You can use the following snippet:

\makeatletter
\providecommand{\H@@footnotetext}{}
\makeatother
\usepackage{hypdvips}

Or you can load the package hyperref with the option breaklinks=true

\documentclass[hyperref={breaklinks=true}]{beamer}
