Not sure if this is the same issue, but it seems that Graphics.Blit is now checking all attached textures to the material, not just those of the pass that is being rendered.
For anyone else having this issue, you can fix it by resetting the temporary texture handles to null, after blitting:
fastBloomMaterial.SetTexture (mShaderIdBloom, rt);
Graphics.Blit (source, destination, fastBloomMaterial, 0);
fastBloomMaterial.SetTexture (mShaderIdBloom, null); // reset reference to temporary texture
RenderTexture.ReleaseTemporary (rt);

I don't think this is a Unity issue. I just upgraded to Beautify 3...it fixed the issue.
