Most likely, this is a timing problem.
  KToolInvocation::kdeinitExecWait()
does not do what you might think it does. It does not wait until the 
program is started or has registered with D-Bus, but it waits until the 
program has finished (or detached).

In any case, you want to use
  KToolInvocation::startServiceByDesktopName("korganizer")
or
  QDBusConnection::sessionBus().interface()-
>startService("org.kde.korganizer")

If you use startService() then you might have to connect to the 
serviceRegistered() signal of QDBusConnectionInterface to get notified 
when korganizer has registered with D-Bus.
