Using the Applications > Accessories > Take Screenshot shortcut on a dual-screen setup, only one of the screens ("Secondary Monitor" in xorg.conf, below) is captured in the resulting image. The screenshot is the correct size, but one side is blank (100% alpha).
Here are the relevant (?) sections from /etc/X11/xorg.conf, as far as I can tell:

Screenshot
I have my internal LCD (1450x1050) on the right and an external CRT (1024x768) on the left. I've added a panel to the left.
See attached screenshot for some cool wierdness.
Note; On the left, the panel IS on the bottom right. I can not see the icons on the left that's revealed in the screenshot (they would show up if I go 'arrange icons')
