[abrt] xfce4-panel-4.10.1-1.fc18: __strcmp_sse42: Process /usr/bin/xfce4-panel was killed by signal 11 (SIGSEGV)
Last modified: 2014-02-05 17:23:50 EST
Description of problem:
It is hard to reproduce this problem reliably. Most of the time, everything works.
When there is a problem, it seems to exist (meaning can be reproduced reliably) until I reboot.
Sometimes, when I click on Application menu -> Settings or Application menu -> Administration, there are no icons in front of the menu entries of the sub-menu.
When I just wait until the icons come up, or when I move the cursor to one of the entries in the sub-menu and wait, the segfault happens.
Yesterday, Application menu ->Settings was affected, today, Application menu -> Administration was affected (meaning: no icons in front of Authentication, Keyboard, ... Yum extender), and just waiting long enough with that sub-menu opened would finally (after about 5-20 seconds) cause the segfault.
If such a problem occurs, I can reproduce it time after time, the only difference being how long I need to wait for the icons to appear or for the entry unter the cursor being highlighted until xfce4-panel crashes.
In some way, this crash could be related to https://bugzilla.redhat.com/show_bug.cgi?id=1003300 and the other bugs mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1003300#c15 and . https://bugzilla.redhat.com/show_bug.cgi?id=1003300#c21.
But today I noticed that xfce4-panel still segfaulted, even though the other programs which segfaulted yesterday,
backtrace always containing either

don't degfault today.
So may be, there's a somewhat higher probability that I'll be able to reproduce xfce4-panel segfaults (assuming that the probability somehow correlates to the number of menus with sub-menus).
As I mentioned above, after another reboot, xfce4-panel doesn't segfault anymore, all the icons in all the submenus are there...

This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. 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bug reports from releases that are no longer maintained.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 '18'.
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 18's end of life.
Thank you for reporting this issue and we are sorry that we may not be
able to fix it before Fedora 18 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, you are encouraged change the 'version' to a later Fedora
version prior to Fedora 18's end of life.
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.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
