I've just tried to reproduce this bug myself (window manager: metacity):
-The OpenOffice window does not get its focus when I click the window tab in the panel.
-Alt+Tabbing however does give the OpenOffice window focus.
Another attempt at reproducing it with xfwm4 for window manager:
-When clicking the window tab in the panel only the activated OpenOffice toolbar gets focus.
-Again, Alt+Tabbing works fine.
