Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Mandriva RPMs

I have reported this bug on the Mandriva bugzilla :
https://qa.mandriva.com/show_bug.cgi?id=45563
I was thinking it was specific to Mandriva. But a comment show that it's reproducible with Fedora. So I report upstream.

Description of problem:
If kickoff hasn't been used during the session, dbus doesn't find it. But after one click on the K menu, kickoff is found. 

Version-Release number of selected component (if applicable):
Mandriva 2009.0 updated

In fact, I don't know if it's a bug with dbus, or with kickoff, or something else... 

How reproducible:
Always.

Steps to Reproduce:
1. Login to KDE 4
2. Run in a konsole : 
$ qdbus org.kde.plasma /kickoff
Cannot introspect object /kickoff at org.kde.plasma:
org.freedesktop.DBus.Error.UnknownObject (No such object path '/kickoff')
3. Click on kickoff to open and close it
4. Run again in a konsole :
$ qdbus org.kde.plasma /kickoff                                                 
signal void org.kde.kickoff.reloadMenu()                                        
method QDBusVariant org.freedesktop.DBus.Properties.Get(QString interface_name,
QString property_name)
method void org.freedesktop.DBus.Properties.Set(QString interface_name, QString
property_name, QDBusVariant value)
method QString org.freedesktop.DBus.Introspectable.Introspect()
