Okular: font issue since update?

Postby linuxsat » 2018-01-09 09:02

Hello,

I am on debian 9.2 stretch with kde desktop on a laptop (DELL 5480),

I have a strange issue with okular: all was alright and now (maybe since the last security update) it doesn't read some of
my pdf files anymore especially those generated by Kile (even those generated a long time ago). Only mathematical symbol and pictures (if any) are displayed, not the text.

I tried with xpdf and also xournal and mupdf, xpdf produces the same result but xournal and mupdf read the files correctly.
Also okular print the files correctly.

I try also to change the fonts in okular back-end options without effect.

Now I edited a latex file with Kile and the problem disappears when the option
Code: Select all
\usepackage[T1]{fontenc}
(used for accents) is not used. Of course in that case the text is not properly displayed (accents are missing).

Kile seems not related to the problem because files are printed correctly and also other readers works properly.

So it seems that the problem comes from okular but I do not know how to solve it?

You are not alone. I'm also affected.

Can either of you provide a link to a sample .pdf that has the problem?

(small would be good, 2-3 pages under 100k if posssible)

Sure! Here you can download a very small example (single page) and its source in lyx and latex formats.

PDF: https://bugs.debian.org/cgi-bin/bugrepo ... pdf;msg=10
LaTeX: https://bugs.debian.org/cgi-bin/bugrepo ... tex;msg=10
LyX: https://bugs.debian.org/cgi-bin/bugrepo ... lyx;msg=10

And here the filled bug: https://bugs.debian.org/cgi-bin/bugrepo ... bug=887793

It seems that there are no text, but you can copy and paste it anywhere (in kate for example) and the text is there.
Evince displays it right but qpdfview has same issue, so I think it's related to poppler backend.

That's an unusual pdf on my system. xpdf doesn't like it, and throws a lot of syntax errors or some such.

It's a v1.5 pdf and I don't have any of those that I can find right away to see if it's an issue like that.

Looking at it with less, it thinks it's a binary, so maybe it is security related.

It's obviously not an okular bug, since it is an issue on several pdf progs. I don't think the qt/kde guys will pay any attention to the bug, but I guess we wait and see.
