If you open the source image up in Gimp or Photoshop and inspect the colour values in the transparent areas, you'll notice they're (255, 0, 255, 0) -- that is, magenta with 0 alpha. When you bilinear interpolate between that and an adjacent non-transparent pixel, the colour is blended as well, giving the pink, translucent outline. You can fix the source images in either Gimp (replace the colours) or programmatically yourself by iterating over the pixel data. AFAIK there is no way to change OpenGL's blending behaviour to have it weight the colour values by alpha.
