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bug reports from releases that are no longer maintained.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.

[bcotton (bcotton-redhat-bugs)]

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no longer maintained, which means that it will not receive any further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
bug.

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

Happened to me after closing Eclipse on fedora 20 x86_64.

[austinenglish (austinenglish-redhat-bugs)]

Still an issue in f20, please reopen. (ABRT redirects here).

[Sebou (radioscope-de)]

I was able to reproduce this issue by plaing with grubs framebuffer settings in /etc/default/grub

When I change it from 640x480 to 1920x1080 for my system specs, this issue appears. When I revert the setting back and reinit everything... the error no longer appears.

Hope this helps.

[Thaddaeus Tintenfisch (thad-fisch-deactivatedaccount)]

Sebou, are you still able to reproduce this crash in Ubuntu 14.04 or up?

[Thaddaeus Tintenfisch (thad-fisch-deactivatedaccount)]

Also, please forward this bug to the Xfce bug tracker. Thanks in advance.
