[Plugin: Sociable] Google 1 is causing unsafe javascript error

Using Chrome’s console to view, I get the following error message if I hover the mouse over the G +1 option when viewing the Sociable plugin on a post.

Unsafe JavaScript attempt to access frame with URL http://globaltradecompliance.net/example-post-of-sharing-a-whitepaper-or-report-available-to-download/ from frame with URL

Domains, protocols and ports must match.

any ideas? The plugin seems to be functioning ok otherwise.
