Comment 7 for bug 543823

1. No, during guest session the icon for gnome-type-monitor looks fine. Also, everything looks very different with black window decorations and such. Switching my main session to Ambience theme didn't help.

2. No, I have yet to face such a problem with any other icon.

3. .xsession-errors has a lot of messages. Most of them are not relevant but these may be:

(gnome-panel:1790): Gtk-CRITICAL **: gtk_icon_theme_lookup_icon: assertion `GTK_IS_ICON_THEME (icon_theme)' failed
sys:1: GtkWarning: gtk_container_foreach: assertion `GTK_IS_CONTAINER (container)' failed
