Alpha on glass is reddish instead of blueish when saving to PNG

[kimmo_hernborg]

I have a glass material set up like this:
*diffuse pure black
*reflection 98% white
*glossiness 1
*refraction 95% white
*ior 1,517
*fog color H 221, S 40, V 100
*depth 4 cm
*effect color and alpha

When I add a white image as background element in the VFB the glass has a blueish tint when its over the white background.
When I save my render as a PNG and add a white background in PS it has more of a reddish greyish tint when its on top of the white background. Objects behind the glass do have the correct bluesh tint however.

I suppose this is a bug?
