Comment 2 Dave Malcolm 2009-12-15 22:57:31 UTC
The backtrace in comment #1 is from /usr/share/abrt/CCMainWindow.py, not from yumex; somewhat ironically, ABRT is crashing with a SIGSEGV whilst trying to display information about a crash inside yumex.

The ABRT SIGSEGV is happening deep inside pango; frame #10 is trying to render textual content within GTK tree/list view, and frame #9 and below is processing the text, trying to calculate the size it will take (in pixels).

Looking at frame #6, it looks like Pango is trying to do linebreaking on a full gdb backtrace from yumex, a rather large string.

Reassigning from "python" to "pango" in the hope of more insight.

Comment 3 Siddhesh Poyarekar 2010-05-17 11:07:32 UTC
This seems more likely to be a glib bug. The traces on bug 587359 and bug 587300 seem to be similar to this, i.e. crashing on a g_slice_alloc. The sources for both those calls are different, one being from gtk and the other being from libsoup.

Comment 4 Bug Zapper 2010-11-04 03:17:07 UTC
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  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bug reports from releases that are no longer maintained.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 '12'.

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 12'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 12 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 5 Bug Zapper 2010-12-04 01:37:33 UTC
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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no longer maintained, which means that it will not receive any further 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.
