Bug 208346

Version:           0.8 (using KDE 4.3.1)
Compiler:          gcc (Ubuntu 4.4.1-4ubuntu1) 4.4.1 
OS:                Linux
Installed from:    Ubuntu Packages

Strange thing here:

I can work normal with kde , the menu , use the panel ...
I open kmenuedit (regardless if I start by right click or in shell)
I can browse the tree (sub-menus..) but as soon as I select an <application entry> kmenuedit suddenly stops working and continues to work after some time.
During that timeout kmenuedit window becomes grey.
During that timeout >>>it is not possible to use the whole panel<<< !
When I wait for 25 seconds kmenuedit is usable again, 
Everything else basically works (save,quit etc.) but with this timeout from now on.
I close kmenuedit now. 
Now comes the really annoying part:
From that time on, the same happens, if I use the search function in kde menu.
I can type a view chars and now also here 25sec timeout until the searched entry is shown in the menu and ready for starting the application.
I have to logout and in again, in order to have the menu search function working again.
All other running applications continue to work normally before,during and after that issue.

strace shows:

It is definitely caused by/or happens only when kmenuedit is used. Also lancelot stops working after using kmenuedit.

I have this "bug" now since about 3 weeks (updated almost on a daily basis)

Maybe someone can have a look or can point into the right direction.
