With the following example

\listfiles
\documentclass{article}
\usepackage{minted}
\definecolor{bg}{rgb}{0.95,0.95,0.95}
\begin{document}
Some text
\begin{minted}{latex}
A test
\end{minted}

Some text
\begin{minted}[linenos=true]{latex}
A test
\end{minted}

Some text
\begin{minted}[bgcolor=bg]{latex}
A test
\end{minted}
\end{document}

the first two code blocks are typeset below the text, but the last one is to the side: Example output

I have Pymentize v1.4 installed, and \listfiles gives

This seems like something that would have been noticed as a bug, so what have I got wrong?

minted uses the following macro internally if a background colour is selected:

\newsavebox{\minted@bgbox}

\newenvironment{minted@colorbg}[1]{
  \def\minted@bgcol{#1}
  \noindent
  \begin{lrbox}{\minted@bgbox}
  \begin{minipage}{\linewidth-2\fboxsep}}
 {\end{minipage}
  \end{lrbox}%
  \colorbox{\minted@bgcol}{\usebox{\minted@bgbox}}}

Without further testing I’m assuming that the use of a minipage doesn’t introduce a new paragraph. If so, a simple \par command before the box should correct the problem.

This seems like something that would have been noticed as a bug,

It should have. The fact is, the documentation minted.pdf pretty much serves as the only test case at the moment and in the documentation the bgcolor option is only used in a single example without surrounding text, so the lack of a paragraph break makes no difference.

Thanks for that Konrad: I'll use a patched version of the environment for the moment. I'm quite familiar with 'use the documentation as a test file' as that is what I do for siunitx. The reason I thought other people might have noticed is that coloured background for code snippets is reasonably common. –  Joseph Wright Jan 17 '11 at 8:16
    
@Joseph: the problem is that coloured background is kind of broken in minted: try having your code span over a page break. This only works properly without background colour, unfortunately, and I’m at a complete loss how to fix that. :-( –  Konrad Rudolph Jan 17 '11 at 9:37

You can solve this issue by making use of mdframed package (\usepackage{mdframed}), this way:

\definecolor{bg}{rgb}{0.95,0.95,0.95}
...

\begin{mdframed}[backgroundcolor=bg]
    \begin{minted}{latex}
        your code
    \end{minted}
\end{mdframed}
