I'd like to point out that this is not window manager specific. I've been encountering this bug with awesome as my window manager (with a custom GNOME 2 session, where panel is set to '' and window manager is set to 'awesome'). If I remove Assistive Technologies from the startup (either by removing at-spi-registry* from the startup applications or toggling assistive technologies off), the bug disappears.
Similarly, running awesome from an .xinitrc/.xsession script without running at-spi-registry also has the bug disappear.
This is on both Jaunty and the most recent Karmic. Emacs is both emacs-snapshot-gtk and emacs-22-gtk.
