[tex-live] Bug#773668: okular shows "jumping" letters in pdf documents generated using pdflatex with russian babel

[Askar Safin]

Package: okular
Version: 4:4.8.4-3+b1
Severity: normal
Tags: l10n

Steps to reproduce:
* Create the following file tex.tex:
\documentclass[a4paper]{article}
\usepackage[russian]{babel}
\begin{document}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed ...
\end{document}
* pdflatex tex.tex
* okular tex.pdf
* Adjust zoom until you will see ugly "jumping" letters (i. e. one letter is up, and the following letter in the same word is down). For example, on my laptop with screen resolution 1600 x 900 pixels and physical size
214.8 cm x 381.9 cm zoom 100 % will go

What I see? Well, "jumping" letters. I see something like this: "LOrEm IpSum DOlOr SIT AmEt ...". See screenshot: http://picpaste.com/y-gh3PH69b.png .

What I expected to see? Normal beautiful text.

Including [russian]{babel} is mandatory to reproduce the bug. [english]{babel} will not go.

But the text itself need not to be in Russian. You don't need even \usepackage[...]{inputenc}.

latex tex.tex + okular tex.dvi - no bug.

latex tex.tex + dvipdfm tex.dvi + okular tex.pdf - no bug.

pdflatex tex.tex + okular tex.pdf - bug.

pdflatex tex.tex + evince tex.pdf - no bug.

pdflatex tex.tex + transfer this tex.pdf to Windows machine + open it with Adobe Reader on Windows - no bug.
