# Wrong scale in a stacked ybar logarithmic plot with basis 10 using package pgfplots

I want the plot described in the title. So I added options log basis y=10 and ybar stacked to the axis environment. The scale becomes wrong. If I add just one option, the scale is right. Is my mistake or a bug in package pgfplots? I am using pgfplots version 1.5.1, and pgf/tikz version 2.10. An example follows.

\documentclass{article}
\usepackage{pgfplots}

\begin{document}

\begin{tabular}{cc}
\begin{tikzpicture}
\begin{axis}[ymode=log
%                , log basis y=10
%                , ybar stacked
]
\end{axis}
\end{tikzpicture}
&
\begin{tikzpicture}
\begin{axis}[ymode=log
, log basis y=10
%                , ybar stacked
]
\end{axis}
\end{tikzpicture}
\\
\begin{tikzpicture}
\begin{axis}[ymode=log
%                , log basis y=10
, ybar stacked
]
\end{axis}
\end{tikzpicture}
&
\begin{tikzpicture}
\begin{axis}[ymode=log
, log basis y=10
, ybar stacked
]
\end{axis}
\end{tikzpicture}
\end{tabular}

\end{document}
