first, thanks a lot for your plugin. Its great! I just use it for a customer. He saw now in his Google Webmaster Tools two links Google wasn't able to follow:
And looks like, when Google tries to follow, it tries badly :D
Anyway, its not really an issue. I will just add some 302 Redirects to this locations for the customer. But maybe you have an idea, how to solve this easily for your next version.
For me its resolved, just to inform you :)
All the best and thanks again, works fine.
