Description Michal Jaegermann 2010-08-03 22:39:35 UTC
Created attachment 436398 [details]
Sample pdf file which evince cannot handle

Description of problem:

evince is unable to display correctly a page using symbols; like on an attached sample.  I cannot confirm that any longer but I do not recall such troubles on Fedora 11.  OTOH the same sample on Fedora 12 also misrenders this page.

What is more on Fedora 13 xpdf got also this affliction while it was spared earlier.

Version-Release number of selected component (if applicable):
evince-2.30.3-1.fc13
evince-2.28.2-2.fc12

How reproducible:
always on a given sample

Additional info:
xpdf-3.02-15.fc13 is as broken as evince.  OTOH xpdf-3.02-15.fc12 is displaying sample page correctly.  As a matter of fact a "correct" sample was done with its help.  Also gv-3.7.1-1.fc13 renders all glyps as expected

Comment 3 Michal Jaegermann 2010-08-03 22:53:57 UTC
Oh, I found why xpdf-3.02-15.fc13 had probles absent for fc12.  It turns out that in /etc/xpdf.config on 13 there was a line 'enableT1lib  no' and this was not the case for 12.  After removing that xpdf-3.02-15.fc13 works as expected.  Does this give any hints about evince?

Comment 4 Marek Kašík 2010-09-17 10:37:30 UTC
Hi,

this looks like a problem in Freetype or the font (GPBFCA+ScienceTypeCustomPi-No5T - 30th stream of the pdf). Poppler uses Freetype to draw chars and running ftview on the font shows only two symbols and "Fails = 18" in terminal (the font contains 20 symbols). Fontforge shows all symbols.
=> reassigning to Freetype

Regards

Marek

Hello,

I would like to add a stone to that problem.
I read articles with evince and sum are in many articles shown as a huge dot.
I think this is related. I remember in F12 this was not true but cannot confirm when the bug appeared exactly?

Comment 8 Michal Jaegermann 2010-11-27 17:19:02 UTC
evince-2.32.0-2.fc14 shows the same issue.  Neither xpdf-3.02-16.fc14 nor gv-3.7.1-1.fc14 have troubles with a sample attached to this report.

Comment 9 Fedora End Of Life 2012-08-16 19:31:16 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
