Comment 22 for bug 211604

I've experienced the same issue and also Alexander Jones' fix works for me too.

A workaround based on savagex post wrote on 2008-06-05 consisits on openning "System>Preferences>Sessions" and on "Startup Programs" tab add an entry like "Name: Trash applet starter; Command: /usr/lib/gnome-applets/trashapplet". Now without Alex's fix also the trash bin applet becomes visible after next session login.
