Glossy refraction alpha bug? Or " feature"

In build 180083 whenever I put a bit of glossiness into the refraction the alpha goes solid. I would expect it to blur to match refraction. Set it to 1 alpha transparent as expected, set it to .99 solid alpha.

Bug?

Build 18083 dec 11 2011

Thanks for the pointer; I thought we’d solved this, but apparently it’s not - will fix it.

Best regards,
Vlado

thanks vlado!
