           Summary: Kontact crashes when clicking "New" if the only active
                    plugin (Akregator) is running as a standalone app
                    [QList,  KontactInterface::Plugin::newActions,
                    Kontact::MainWindow::slotNewClicked]
           Product: kontact
           Version: 4.4 pre
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: andresbajotierra at gmail.com

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.
