If every window manager except KWin behaves as expected, I guess it's 
KWin's fault.

But maybe nothing in the freedesktop standard says that a window that is 
not shown in the taskbar must not be visible with ALT+TAB... It's just 
KWin that is less clever than the others, and I cannot do anything 
against that.

You should fill a bug on bugs.kde.org, or ask on the KWin KDE 
mailing-list and see what they say.
