Bug 456665

Oh fun... It seems each time one problem with GTK+ systray icons in KDE gets 
fixed, another comes up. :-(

with mugshot-debuginfo (and friends).

I'm pretty sure this has nothing to do with the KDE systray, and quite
likely nothing to do with KDE at all. I've actually seen pretty similar
looking crashes with GNOME (and i386), though not reliably reproducable.

I'd suggest removing it from the KDE 4.1 tracker.

Thanks for clearing that up.

Hmm, what version of mugshot and hippo-canvas? I think the mugshot
from updates might incompatible with hippo-canvas from updates-testing.

rpm -q mugshot hippo-canvas
mugshot-1.2.1-1.fc9.x86_64
hippo-canvas-0.3.0-2.fc9.x86_64

confirmed that downgrading to
hippo-canvas-0.2.34-1.fc9.x86_64
from (stable) updates makes mugshot functional again.

I'll push a mugshot rebuild to updates-testing

mugshot-1.2.2-1.fc9 has been submitted as an update for Fedora 9

mugshot-1.2.2-1.fc9 confirmed mm, mm, good.

mugshot-1.2.2-1.fc9 has been pushed to the Fedora 9 testing repository.  If problems still persist, please make note of it in this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update mugshot'.  You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F9/FEDORA-2008-6923

mugshot-1.2.2-1.fc9 has been pushed to the Fedora 9 stable repository.  If problems still persist, please make note of it in this bug report.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  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bug reports from releases that are no longer maintained.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 '9'.

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 9'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 9 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
