Domain Mapping apparently causing problems with switch_to_blog

Hi,
I'm having some problems using the switch_to_blog function when a domain is mapped with your domain mapping plugin.

I've installed a small bit of code that does a check with the switch to blog function.

Here's the result on a non-mapped website:

$current_site (Main Blog) Details
Main Blog ID ($current_site->blog_id) : 1
Main Blog Name ($current_site->site_name): langhe.net

Current Site Details
Current Site ID : 130
Current Site Name : Shop Langhe

After switching to main blog using switch_to_blog(1);
Current Site ID : 1
Current Site Name : Z>>>Langhe.net<<<Z

After restoring current blog using restore_current_blog();
Current Site ID : 130
Current Site Name : Shop Langhe

And here's a result of a domain mapped website

This snippet tests your site for MultiSite and makes sure blog switching works.

$current_site (Main Blog) Details
Main Blog ID ($current_site->blog_id) :
Main Blog Name ($current_site->site_name): langhe.net

Current Site Details
Current Site ID : 70
Current Site Name : Ambiente & Cultura

After switching to main blog using switch_to_blog();
Current Site ID : 70
Current Site Name : Ambiente & Cultura

After restoring current blog using restore_current_blog();
Current Site ID : 70
Current Site Name : Ambiente & Cultura

Did anybody experience something similar?

thanks!
