Description Dario Andres 2009-12-17 02:54:04 UTC 
Application: kontact (4.4 pre)
KDE Platform Version: 4.3.82 (KDE 4.3.82 (KDE 4.4 >= 20091211)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Qt: 4.6.0 (kde-qt master commit 784477685913781462c426e99605546a4beaf3a4
        Date:   Tue Dec 1 19:17:20 2009 +0100)
KDE Development Platform: 4.3.82 (KDE 4.3.82 (KDE 4.4 >= 20091211))
kdelibs svn rev. 1062703 / kdebase svn rev. 1062703
kdepim svn rev. 1060455
on ArchLinux i686 - Kernel 2.6.31.6

Steps to reproduce:
- Start Kontact
- Disable all the plugins (the only remaining one will be Akregator)
- Close Kontact
- Start Akregator as a standalone application
- Start Kontact
The "New" action in the toolbar now has a "unknown" icon. 
- Click the "New" toolbutton 
Kontact crashes

(note that Akregator is not accesible from Kontact if it is already running as a standalone application)


The crash can be reproduced everytime.

According to bug 227300, this can also happen with KMail (if it is externally running)

I am not sure that the crash is exactly as the earllier bug reports report.But all the conditions match.I have both Akregator and Kmail and (Korganizer too) running as separate applications.

Comment 7 Denis Kurz 2016-09-24 19:24:29 UTC 
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kontact (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
Comment 8 Denis Kurz 2017-01-07 22:45:25 UTC 
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
