iconbox: "bug" ?

[Danny]

I just noticed something:

If a window changes its title, then this new title is now shown in the
iconbox (for the icon hint).

I tried that with an xterm, which sets its title depending on the
current directory.
However in the iconbox it always says "xterm", and not the modified
title. In the title bar of xterm, it says the modified title, and in the
Alt+Tab task switcher as well.
