gnome-screenshot ignores "--area" if called from shortcut

By pressing "Print" a screenshot of the whole desktop gets taken. But I would prefer if I could always choose the area of the screenshot by hand. By calling "gnome-screenshot --area" from commandline you can select the area.

So I went into System -> Shortcuts (? have a German layout) and deactivated the shortcut "print" for taking a screenshot.
Now I added a new shortcut with the command: "gnome-screenshot --area" and assigned the "print" key to it. (Theoretically I am done at this point)

 But if I press the print key a screenshot of the whole screen gets taken. And there was NO area selection. If I change the command from "--area" to "--interactive", then by pressing the "print" key the property window pops up (if i select there the checkbox area-selection I can choose the area). Assigning "gnome-screenshot --area" to a different key/ or combination of keys has the same result - the area selection never shows up. (The interactive mode always works)

Do I miss something or did I found a bug? And can anyone tell me if there is a fix?

As a workaround I tried putting the command into a script and then calling the script per shortcut with the same result: the area selection never shows up, (the interactive mode does).

I am using
Ubuntu 9.10 with kernel 2.6.31-20-generic (without compiz or any desktop effects)
