Application: kmail (2.0.95)
KDE Platform Version: 4.6.41 (4.7 >= 20110106) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.38.5optimum x86_64
Distribution: "openSUSE 12.1 Milestone 0 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

NOTE: Compiled with gcc 4.6.0

I just start kmail, the window body is painted and the crash is there.

I reported the bug to Qt people, 

http://bugreports.qt.nokia.com/browse/QTBUG-18986?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

But when I try to make the simplest program to crash it:

  #include "imapsettings.h" // generated by qdbusxml2cpp
  QScopedPointer<OrgKdeAkonadiImapSettingsInterface> interface( 
  new OrgKdeAkonadiImapSettingsInterface( "org.freedesktop.Akonadi.Resource.kk",
                                         "/Settings", QDBusConnection::sessionBus() ) );
  
  if (interface->safety() == &hi ) ;

I get the following compiler error:
undefined reference to `OrgKdeAkonadiImapSettingsInterface::OrgKdeAkonadiImapSettingsInterface(QString const&, QString const&, QDBusConnection const&, QObject*)'

I've searched for OrgKdeAkonadiImapSettingsInterface constructor, and the only one I see is in imapsettings.h and is empty. 
From where does kmail get the OrgKdeAkonadiImapSettingsInterface constructor?

The crash can be reproduced every time.
