slickswitcher crashes on startup

[Luca Dariz]

I'm using debian squeeze with awn and awn-extras from repository and with gnome/compiz.

here's the backtrace:
** (avant-window-navigator:2093): DEBUG: Spawned awn-applet[4654] for "slickswitcher.desktop", UID: 1311500192, XID: 37748785

I attach compiz's config files
