Redirect loop with Global Redirect and Spaces OG

I'm getting a redirect loop when I try and visit a newly created group node. The group node would normally be accessible at node/175, and Spaces OG redirects it to [path]/node/175, where [path] is the "Path" field that Spaces OG adds to the group node creation page. Global Redirect catches this, judging that it's a duplicate URL, and redirects back to node/175, which Spaces OG again redirects.

Edit: Upgrade to 6.x-1.4 - wasn't mentioned specifically in the notes, but it seems the other redirect loop problems had the same cause.
