# Manual line break in beamer \title adds spurious comma in \inserttitle

Currently I'm preparing a presentation with the beamer class. I want to add a manual line break (with \\) to the title to make it look nicer. However, in the \inserttitle command (which I use in the footer), the line break adds a spurious comma.

Is this a bug or a feature? How do I get rid of the comma?

Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  Jubobs Oct 29 '13 at 20:40

I believe that this is an intended feature of beamer (you don't want a line break in the footer anyways, do you?). Well, have you tried this?
\title[My long presentation title]{My long \\ presentation title}

Of course, you need to use \insertshorttitle instead of \inserttitle.
