Actually, that is the bug in GIMP:

The image uses an indexed palette and an alpha channel. In GIMP 2.8, this limits the alpha to binary, i.e. 
fully opaque or fully transparent. If you look at the image in other application, it is smooth there already.

When you change the mode to RGB, the alpha channel is displayed as it is supposed to be.
