On EeePC panel will not resize correctly after external monitor disconnected

Bug Description

Binary package hint: gnome-panel

[Problem]
Can get into situation where gnome-panel cannot be made to resize properly via 'rm ~/.config/monitors.xml; pkill gnome-panel'

[Steps to Reproduce]
1. Start X on EeePC with external monitor (projector) attached at 800x600
2. The projector display works, but the LVDS is blank
3. 'xrandr --output LVDS --mode 1024x600' brings back the display onto LVDS at the specified resolution, however the panel is sized to 800 horizontal width
4. Disconnect the external monitor.
5. Check that there is no ~/.config/monitors.xml.
6. 'pkill gnome-panel' makes gnome-panel restart, but panel still comes back at a width of 800.

[Workaround]
Restart metacity or compiz, then pkill gnome-panel and it comes back fine.

[Expected Behavior]
When killing gnome-panel, it should note that only the LVDS is active and is set to 1024 width, and display itself at that width.

[Ideal Behavior]
Something should detect that the monitor was disconnected, and automatically resize gnome-panel at that point.
