I have installed Sabayon 6 K with KDE 4.7.0

In the last weeks I've been trying to fix two things:
1. the file associations
2. the KDE menu

Both look frozen.
I open system settings>file associations and remove or try to change default editor for text. They seem changed first, the updating progress dialog appears, apparently no error occurs, until I close the file association window. If I come back they are as in the first place. Dolphin has the same "open with" content.

I have tried to add some new entries to the KDE menu, using "Edit applications" context menu.
There is no success. It has similar behavior as file associations. Looks updated in the KDE menu editor, but none occurs in fact.
Also, I have installed many apps, like Calligra, VirtualBox, gparted, foobillard, Kate. They have created no entry.

This becomes a mayday situation. I don't intend to re-install everything.

Does anybody has a solution, hint, idea, similar situation?

Thank you,
Mike

That sounds pretty strange, maybe a permission problem. Can you reproduce with a new user?

Also, try running "kbuildsycoca4 --noincremental" to purge any out of date cache issues which may be preventing the edit from taking effect.

I've tried kbuildsycoca4 with no success.

I've created a new user, some of the lately installed apps become available in the menu, I could create a new menu entry and a new menu item entry.
But I couldn't have it in the intended place, somewhere between existing ones, but it stays at top always.

Could be my distro errorneous install, but I don't know how could I check that. I couldn't find anything in logs.

I would like to know which are the config files involved.

The menu is a composite of many elements. The actual menu folders come from *.menu files, which themselves can be sourced from many locations. The items in the folders come from *.desktop files, which can be also sourced from many different locations.

They are usually /usr/share and ~/.local/share
