    Bug 555109 â?? selection broken when typeahead active
    
    gtk_tree_view_enter_notify() now "ignores" the synthesized crossing
    events.  The synthesized crossing events always have (0, 0) as
    coordinates, which messes things up.  This patch does not fix all issues,
    at least it makes the behavior much more reasonable again.  Watch bug
    555109 for further discussion on the issue.
