Problems with domain mapping plugin

Hi,

i'm running into weird problems with the domain mapping plugin. I found google to index some of my sub.domain.com blog url's even though they are mapped to mappeddomain.com. I checked with Firefox Live HTTP Header and found out that they are redirected through 302 instead of 301 http header.

I walked through the plugin code and found that the redirection is - instead of Donnchas mapping plugin) hardocded into 301.

But hey, why are my blogs then redirecting with 302?

Anyone with an idea out there?
