Core dump.

Description of problem:
While reading pdf files, evince has a segmentation fault. Not exactly sure how to reproduce, but I seem to hit it fairly often (a number of actions, not sure which one actually triggers it.)

Version-Release number of selected component (if applicable):
[root@mordor ~]# rpm -qv evince
[root@mordor ~]# 

How reproducible:
Extremely, but not sure of which exact action causes teh segmentation fault.

Steps to Reproduce:
1. Selecting a lot of text and scrolling at the same time.
Actual results:
Evince crashes

Expected results:
Evince should not crash.

Additional info:
I've a core dump. Attaching it. The gdb backtrace shows the following,
Core was generated by `evince keynote.pdf'.
Program terminated with signal 11, Segmentation fault.

proposed patch

this is a bug in poppler.
It is caused by different sizes of bounding boxes of words and bounding boxes of lines.
This can happen for a special character in a line. Height of the bounding box of such line is then higher than bounding boxes of normal words.
If user double clicks in the space inside bounding box of such a line, but outside bounding box of the closest word, then the application crashes.
(it crashes after searching for the beginning of the selection, because beginning word is not hit but it is supposed that it was hit)
The attached patch avoids crashing by cancellation of such a selection.

modified patch

This version of the patch was accepted by upstream. (for actual rawhide version (F11))


Comment 4 Bug Zapper 2008-11-26 02:54:47 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

More information and reason for this action is here:

Comment 5 Marcel Ziswiler 2009-02-04 19:08:57 UTC
I got evince to crash as well on my up-to-date FC10 x86_64 system. I think I was using the search feature when it happened. I had lots of PDF documents opened. All of them closed upon this crash which is rather sad.

Comment 7 Bug Zapper 2009-11-18 08:20:33 UTC
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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: 

Comment 8 Bug Zapper 2009-12-18 06:21:06 UTC
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
