Description Adam Pribyl 2005-12-17 20:41:24 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.7.11) Gecko/20050728

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):
kdebase-3.5.0-0.1.fc4

How reproducible:
Sometimes

Steps to Reproduce:
1. start KDE: startx -- :1
2. play with something for a while
3. logout
  

Actual Results:  Here is KCrash output:
(no debugging symbols found)
Using host libthread_db library "/lib64/libthread_db.so.1".
(no debugging symbols found) 23x

Logout is delayed as kicker is restarting...

Expected Results:  Obvious.

Additional info:

Clean profile, no changes in KDE.
Comment 1 Niko Mirthes 2005-12-18 23:35:44 UTC 
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.
Comment 3 Adam Pribyl 2005-12-19 13:18:28 UTC 
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.
Comment 4 Niko Mirthes 2005-12-19 22:12:20 UTC 
This is already fixed in rawhide, apparently. In the future, it'd be nice to get
some feedback from someone so people can avoid wasting time and effort.
Comment 5 Luc Lalonde 2005-12-20 16:54:59 UTC 
I confirm that the patch fixes kdelibs-3.5.0-0.1.fc4.

Thanks
Comment 6 Than Ngo 2005-12-21 11:53:34 UTC 
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!
Comment 7 Niko Mirthes 2005-12-21 17:14:45 UTC 
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
future?
Comment 8 Than Ngo 2005-12-21 17:19:20 UTC 
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.
Comment 9 Adam Pribyl 2005-12-22 18:19:21 UTC 
Seems fixed, thanks.
