Document Classes ⇒ vfill in beamer columns

[jazzgossen]

I want to put some text at the bottom of a slide in a beamer presentation. I've tried various versions of \vfill, \vspace{\fill}, \vspace*{\fill}. None seems to work the way I'd expect.

Code: Select all

\documentclass{beamer}
\begin{document}

\frame 
{ 
  \frametitle{A title}
  
  \begin{columns}[t]
    \begin{column}{0.65\textwidth}
      \begin{itemize}
      \item An item.
      \end{itemize}
      \vfill
      Text at bottom.
   \end{column}
 \end{columns}
}

\end{document}

If I remove the column environments, some space is inserted at the \vfill, but the text is still not placed at the bottom. Inside the column environment (and I do want to use columns), no space at all is inserted by the fill commands.

How can I make sure that the text is placed at the bottom?
