- Start Gimp (need a fresh Gimp instance)

- Add an alpha channel to the white background
- Make a rectangle selection that covers on half of the rectangle
- [delete]
- You should know have a layer which is pure white on one half andfully transparent on the other
- Using the pointer dialog you can verify that the transparent bit is still 255,255,255, only the alpha changed.
- Remove the selection
- Filter>Blur pixellize and use a tile as big as the image (800x800)
- Use the pointer dialog again. The image should be a very drak gray (I get 44,44,44) with an alpha of 127.
Now, do the same thing on a small image (200x200). Your result should be half-transparent white
(255,255,255,127). If you confirm this I'll file a bug...
Confirmed. I followed your steps and the outcome is exactly the way you describe it.

It worked on a white BG with a black circle, but when i used a red BG with a green circle, i was left with a border again.
Did you set Gimp's paint background color to match (for instance using the color picker) before calling the script?
