When you try to subscribe to any of the pre-defined RSS Feeds, you'll end up sending a "bad request".

Steps to reproduce:

1. Go to Spaces
2. Choose any space
3. Go to Space tools > Content Tools > RSS Feeds tab
4. Choose any link from the list

Expected outcome:

You should be presented with an XML content

Actual outcome:

You are presented with a HTTP Status 400 - Bad Request (due to a title surrounded with squared brackets)

 Workaround:

Delete the [] squared brackets that are surrounding the title name and it will work as expected.
