Bug#659772: landscape sciposter + hyperref + latex + dvips = center-mirrored image

[<jaakov@ro.ru>]

Package: texlive-binaries
Version: 2009-11
Severity: important

1. Create a fresh file, say, q.tex, with the following contents:
\documentclass[landscape]{sciposter}
\usepackage{hyperref}
\begin{document}
abcABC
\end{document}

2. Run
 latex q && dvips -o q.ps q.dvi

3a. Run
   gv q.ps &
 or
   evince q.ps &
 Observe that the abcABC is center-mirrored in the right lower corner. 
It should not be.
3b. Run
   xdvi q.dvi
 or
   evince q.dvi
 Observe that the image is normal, not mirrored. So, most probably, the 
error happens in dvips.

At step 1, removing either the landscape option or not including the 
hyperref package results in a normal image as expected.

I would be grateful if anyone with more insight into the interplay 
between sciposter, hyperref, latex, and dvips could repair this issue.

Best regards

Jaakov.
