Mighty strange. KOffice used to work ever since the new iconloader was 
introduced.  Currently, I don't have the time to compile koffice because on 
wednesday I'm going on Interrail for 1 month. Let's hope we can clear this 
up before wednesday.

The weird directory structure is for themed icons. It allows for the 
drop-in replacement of the entire KDE icon set. I didn't hear of any drop 
in icon set yet, but it is certainly cool for themes etc.

An overview of the entire icon loader can be found at:

http://developer.kde.org/kde2arch/iconloader.html

Please read it, it will explain everything :)

This latter directory is for "unthemed" icons. I don't know why konqy is 
using these, though. I think it should install the icons in the theme 
directories, so they can be replaced by a (3rd party) icon theme.

I compiled a small test app (attached) and it works for me. This will 
illustrate how the iconloader works. Can you try it and see if it works? It 
will find the kword icon installed in
$KDEDIR/share/apps/kword/icons/locolor/22x22/actions/sl_addentry.png

PS: It is important that you add the right dirs with "addAppDir". This is 
done automatically for the instance name. Kword adds "koffice" itself. This 
way, for example, Kword should find the icons in share/apps/kword/icons/* 
ands hare/apps/koffice/icons/*. (and of course the "global" icons in 
share/icons/*)

Greetings,
Geert
