We have logged it to our system.
In order to prevent it, you may define:
1. Url rewrite rules that match an url different than the home page, and containing a slash at the end. If such request is found, then you should be redirected to the matched url without the slash.
2. Http module doing the same.
We will try to fix it as soon as we can. Thank you once again!
