Figure or longtabu/longtable causes bottom margin overflow

Question

I have been searching for a while now without any luck, so I hope you can help me. The problem is that when I insert a figure/longtabu on my page, the text below is running out of the page, like this image shows:

Do you know what the problem is here?

Apparently longtable had some issues on calculating the size of the page when a float is on the same page. I modified my longtable.sty file according to the instructions and now all is splendid, once again! :D

Answer 2

I have no idea what is going on here. But I've reduced it to the following

It seems to be longtable related. I'll retag the question.

\documentclass[a4paper,twoside,11pt]{article}
\usepackage{longtable}
\usepackage{lipsum}
\usepackage[demo]{graphicx}
\begin{document}

\lipsum[2]

\begin{longtable}{ l }
  A\\A\\A\\A\\A\\A\\A\\A\\A\\A\\A\\A\\
\end{longtable}


\lipsum[1]

\begin{figure}[htp]
    \centering
    \includegraphics[width=1\linewidth]{KDBrugafDDGFW}
    \caption{sss}
    \label{fig:KDBrugafDDGFW}
\end{figure}

\lipsum[1]

\begin{longtable}{ l }
  A\\A\\A\\A\\A\\
\end{longtable}

\lipsum
\end{document}
