Clock applet not showing on the correct location when in bottom panel

Binary package hint: gnome-panel

I'm using gnome-panel 2.30.2-1ubuntu3.

When clicking on the clock applet positioned on a panel with bottom orientation, the time/weather/calendar window shows up as if the clock applet is in a top panel.

The expected behaviour would be to show up on the bottom of the screen, near the clock applet.

I've included a screenshot showing the bug.
