Description Elias Probst 2015-01-11 23:20:55 UTC 
Application: kded5 ()
 (Compiled from sources)
Qt Version: 5.4.0
Operating System: Linux 3.18.2-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
When opening a new incoming KTP conversation by clicking on the "New conversation" notification in the systray (Breeze theme: pulsating envelope), kded5 will crash with this backtrace.

KF5/Plasma 5/KTP is all from git and up-to-date.
Qt 5.4.0

The crash can be reproduced sometimes.

-- Backtrace:
Application: kded5 (kded5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

*** Bug 343508 has been marked as a duplicate of this bug. ***
Comment 2 Martin Klapetek 2015-01-29 12:33:54 UTC 
Hmm...I could really use a way to reliably reproduce this one. I'm not really sure why this crashes as apparently things are not null.

Does it crash often enough so that if I give you a patch spitting debug output, you could give me that output?
Comment 3 Albert Astals Cid 2015-01-29 19:21:47 UTC 
I got it twice in 5 minutes in konsole, then not again in the whole day.

Fix dangling pointer to KNotification

notificationQueue may contain dangling pointer to KNotification, clean
up when notification is closed.
galagoNotifications may also contain dangling pointer, use QPointer to
protect the access to KNotification.

Guys, can anyone of you reliably reproduce this crash (I can't)? And is anyone able to test simple patches?

Comment 17 George R. Goffe 2015-05-09 19:53:36 UTC 
Martin,

I would be willing to try to test patches.

This sounds like source code patches, am I right? I had trouble building KDE from sources some time ago... What form would the patches be in? RPM? This would be best for me since I could recover by "yum/dnf reinstall".

George...
Comment 18 George R. Goffe 2015-05-09 19:56:25 UTC 
Hi,

I was having trouble with KDE NOT INITIALIZING (plasmashell crashing). Thanks to Christoph for pointing that out.

I went to this site "http://kde-redhat.sourceforge.net/" and found a kde repo
with newer(?) contents. Here's the link to that. I installed this in
/etc/yum.repos.d/ and then did a "dnf update". Approximately 163 packages were
installed. I then rebooted and tried the procedure I'm interested in, namely
with "startkde" in .xinitrc. I did a startx and KDE came right up. There are
some minor problems in the software but IT CAME RIGHT UP!

I'm a happy camper.

Does any of this help anyone?

The repo file:

http://apt.kde-redhat.org/apt/kde-redhat/fedora/kde.repo
Comment 19 Martin Klapetek 2015-05-11 11:47:23 UTC 
Sorry, I have no idea about RPM's or Fedora's repos. Testing patches is possible/easiest only when you're actually running latest master already built from source by using eg. kdesrc-build.

Nevertheless, I think I now know what's going on, I should have a fix shortly.
Comment 20 Martin Klapetek 2015-05-12 12:00:31 UTC 
Fwiw, here's the patch if anyone feels like testing - https://git.reviewboard.kde.org/r/123731/

Well...I don't this it does. I think bug 398695 is a duplicate and would like someone else to verify.
Comment 40 Nicolas Fella 2020-11-23 00:45:20 UTC 
From the lack of new reports I'd say this is resolved
