restbuilder fails with URL

[cvergari]

Hi, I have been having a difficult to interpret error message when compiling a project:

writing output... [100%] index
Exception occurred:
  File "C:\ProgramData\Miniconda3\envs\sphinx\lib\site-packages\docutils\nodes.py", line 652, in __getitem__
    return self.attributes[key]
KeyError: 'name'

I was able to track it down to this very minimalistic RST source file:

This is a link: http://www.google.com

This source fail fails to compile. However, this one works:

This is a link: www.google.com

I should also mention that the standard HTML compiler works.in both cases.
