Graphics, Figures & Tables ⇒ slight bug with fbox around figure

[Faust]

When I use the following code:

\begin{figure}[H]
\centering
\setlength\fboxsep{0pt}
\setlength\fboxrule{0.5pt}
\fbox{\includegraphics{article}}
\caption{Een actuele nota van een grote partij water (600l).}
\label{receipt}
\end{figure}
I get a nice tight frame around my figure

HOWEVER when I rescale the figure using:

\begin{figure}[H]
\centering
\setlength\fboxsep{0pt}
\setlength\fboxrule{0.5pt}
\fbox{\includegraphics[scale=0.5]{article}}
\caption{Een actuele nota van een grote partij water (600l).}
\label{receipt}
\end{figure}

the box is slightly moved to the left leaving a small white space between the frame and the picture. How should I deal with this?

Is there an option to rescale the complete float?
