Bug#519215: gnome-panel: gnome panel does not auto-hide correctly

[Kejia]

Package: gnome-panel
Version: 2.20.3-5
Severity: normal

When I invoke some program from tray panel, the auto-hide-configured panel besides the tray panel does not hide until the cursor point touches it again. For example:
1) Of course, set the panel besides the tray panel to auto-hide;
2) Run Tomboy Notes and minimize it to the tray panel;
3) Click the Tomboy Notes' icon at the tray panel and choose pop menu item search all notes.
Then the panel does not hide.
