More specifically, this occurs when the mouse cursor is placed over a currently
disabled toolbar button that later on gets enabled. Then the button isn't
clickable until you move the cursor away from the button and then hover it over
the button again. This is a separate bug, but if it isn't filed already, it
should be reported. I've been annoyed by that bug since the early days of Ubuntu
(although this is most certainly a Gnome/GTK bug). :)
