You can also achieve the same result using paint tools.

1 - Eyedrop the background color.
2 - Switch to the Paintbrush and the "color erase" blending mode.  Color erase is also a color-to-alpha transition.
3 - Start painting the background.

Hmm... this begs the question: what is the difference between "Colors/Color-to-alpha" and the bucket-fill tool in color-erase mode?

I believe "Colors/Color-to-alpha" will remove the color from the entire image, not just from a selection.

Peace...

Here's a link to the documentation on "Color to Alpha":
