Since akonadi has been implemented (previous versions of kde and current), when you start kmail as root user (kdesu) under normal user, it no more possible to run kmail.

I used kdesu-kmail to have access to service mail without having to logout, shutdown the XServer and than start root and kde and kmail.


Reproducible: Always

Steps to Reproduce:
1. Login as normal user without root priviligies
2. Start kde
3. Create a link to application with :
    [Desktop Entry]
   Comment[en_US]=
   Comment=
   Encoding=UTF-8
   Exec='/usr/bin/kmail'
   GenericName[en_US]=
   GenericName=
   Icon=kmail
   MimeType=
   Name[en_US]=SU E kMail
   Name=SU E kMail
   Path=
   StartupNotify=false
   Terminal=false
   TerminalOptions=
   Type=Application
   X-DBUS-ServiceName=
   X-DBUS-StartupType=multi
   X-DCOP-ServiceType=none
   X-KDE-SubstituteUID=true
   X-KDE-Username=root

4. Run the link
Actual Results:  
Cannot launch kmail as root from common user

Expected Results:  
Launch kmail from normal user with root priviligies.

Nothing
