Bug Description

Binary package hint: okular

Kubuntu 8.10 with all upgrades.

In Okular open a DVI file created with LaTeX, nothing fancy, black and white text, which uses "times" font and open Thumbnails. When the size of the thumbnails is sufficiently big, the thumbnails look fine. When the size of the thumbnails is small, 40% of the area of the thumbnails becomes uniformly read (impossible to see the thumbnail). Not every DVI file with "times" font has this problem; it seems that the "density" of text per page should be big enough.

The problem does not concern PDF nor PostScript files.

I created a simple LaTeX document using the default Computer Modern fonts. When viewing the resulting DVI in Okular, the thumbnail preview is full of big red boxes. (See attached screenshot.)

The bug does not occur when using PostScript fonts (e.g., by specifying \usepackage{times} in the LaTeX document). It also doesn't occur when viewing PostScript or PDF representations of the document. The problem may be related to the font encoding.

I'm attaching the original LaTeX file and DVI.

Upon further study, I have further narrowed down the cause of the problem: The red boxes appear wherever there is a period character (.) when using Computer Modern fonts with certain font encodings. Here is a minimal example:

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
.
\end{document}

Add more periods to get more red boxes. The following font encodings produce red boxes:

T1
T2A
T2B
T2C
TS1
X2

The following font encodings do not produce red boxes (at least, not for the . character):

IL2
LCY
LGR
LMC
LO1
LY1
OML
OMS
OT1
OT2
OT4
T2D
T3
T4
TS3

Please attach a DVI that works. Thank you.

Indeed, the problem occurs only with documents using certain fonts. In this case its "times" fonts which can be installed from the standard repository by:

sudo aptitude install texlive-fonts-extra

I'm confused. Now, just 1hr later, I don't see them any more on the same file...

I'll will try to narrow it down.
