fresh installed GUI application does not appear in KDE menu

[Orcan Ogetbil]

How to reproduce:
- Install the latest KDE 4.2.0 from kde-redhat-testing *
- Install any GUI application that comes with a
/usr/share/applications/*.desktop file via yum

Actual result:
The application doesn't appear in the KDE menu until re-login

Expected result:
The application shows up in the KDE menu rightaway (well maybe with a
slight delay, but surely one shouldn't have to log out and back in).

I am 90% sure that this problem didn't exist in KDE 4.1.9? versions.
Can you confirm this?
