gnome-screensaver locked pointer as a crosshair

[themusicgod1]

(i've seen it do this before but it only happens very rarely)

what should happen:

1) run gnome-screenshot
2) it presents a little window of which kind of screenshot you want to take
3) select 'select area to grab'
4) the pointer is replaced by a crosshair and you can't click on anything except with that crosshair to select an area
5) after you are done selecting an area, the screenshot is taken and the cursor is returned to normal along with its functionality

what happened instead:

5) the pointer got stuck in this crosshair (only on particular areas of the screen though, the dock(?) and a couple other windows like audacious.

ironically

ubuntu-bug got the pointer back into a pointer again
but it still seems stuck and unable to click on icons such as the screenshot shortcut icon, changing the active window (unless you click in a text field), dragging windows around (alt-tab still works)
