[Tex/LaTex] \includepdf changes left and right pages

double-sidedprintingsectioning

I've followed advice at "How to start new chapters on the right hand side" and found that including as title page, one PDF page is braking left&right orientation:

\documentclass[pdftex,a4paper,12pt,twoside,openright]{report}
\usepackage[pdftex,a4paper]{geometry}
\usepackage{pdfpages}
\usepackage{lipsum}
\begin{document}
\includepdf{onetitlepage.pdf}   % <---- problem
\begin{abstract}
Abstract \lipsum[1]
\end{abstract}
\tableofcontents
\chapter{CH1}
\lipsum[2-6]
\chapter{CH2}
\lipsum[7-8]
\chapter{CH3}
\lipsum[9]
\end{document}

After including one page PDF, I get same document, but with one more page on beginning. It's all right except one thing: right pages are now left pages.

My current workaround is to include additional empty page, like that:

\includepdf{onetitlepage.pdf}
\includepdf{oneemptypage.pdf}   % <---- current solution

Is is LaTeX-y way?

Can it be done in more elegant, LaTeX-y way?

What is the reason why including onepage.pdf breaks left&right hand side,
and how to prevent it when writing documents?

Put \cleardoublepage after \includepdf. Also, specify the notitlepage option, so the abstract will not start anew the page numbering.

\documentclass[a4paper,12pt,twoside,openright,notitlepage]{report}
\usepackage{geometry}
\usepackage{pdfpages}
\usepackage{lipsum}
\begin{document}

\includepdf{onetitlepage.pdf}
\cleardoublepage

\begin{abstract}
Abstract \lipsum[1]
\end{abstract}

\tableofcontents

\chapter{CH1}
\lipsum[2-6]
\chapter{CH2}
\lipsum[7-8]
\chapter{CH3}
\lipsum[9]
\end{document}

Never specify the pdftex option (there are cases where it's necessary, though, in connection with geometry and crop, but it's not your case).
