Description of problem:
You could treat this as duplicate of #160740, but this report is about latest update to KDE 3.5 in FC4 - maybe some KDE regression. Till that day I never saw kicker crashing at logout, now it is almost every time. Could be x86_64 specific.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. start KDE: startx -- :1
2. play with something for a while
Actual Results: Here is KCrash output:

Using host libthread_db library "/lib64/libthread_db.so.1".

Logout is delayed as kicker is restarting...
Expected Results: Obvious.
Clean profile, no changes in KDE.
According to the upstream maintainer, this bug is known. Apparently it was fixed
for release, then mistakenly reverted prior to tagging for KDE 3.5 release. It's
fixed upstream in KDE's svn repo, so a patch can be made, or wait for 3.5.1.
I believe this can be avoided by not adding any (or removing any existing)
Action menus to the main menu (kmenu). These can be added and removed in Control
Center (kcontrol), found in the "Option Menus" at Desktop -> Panels -> Menus

Attempt at fixing kicker (panel) crashing on logout
I've gone ahead and made a diff against upstream that seems to fix this
problem. I've been using it for the last few hours and it seems fine so far.
Thanks for all your attention. I am sorry I can not help you with testing of
this patch, but if there is any rpm devel build I can test it.
This is already fixed in rawhide, apparently. In the future, it'd be nice to get
some feedback from firstname.lastname@example.org so people can avoid wasting time and effort.
I confirm that the patch fixes kdelibs-3.5.0-0.1.fc4.
Niko, many thanks for the patch. I don't think it's fixed in the rawhide,
because it's the same tar file from FC4!
Oh, ok. Thank you, Than. Someone in #fedora-devel on freenode seemed to think it
was fixed in rawhide. Any chance of applying this patch and updating in the near
i even built new kdelibs with this patch in rawhide. it should be available in
rawhide soon. For FC4 update, it will be pushed out this weekend.
Seems fixed, thanks.
