Unable to create a new repository: process appears to hang

I've tried to create jfine/python-argtools repository and I get a web page that says:

The repository has been created.

Creating!

We're creating your repository right now, and it shouldn't take long. If it takes longer than a few minutes to complete, please visit the admin-page for this repository and delete it, then try again.
Loading...

This page will reload itself continuously until it's done.

I tried to clone the new repository:

{{

{ $ hg clone https://jfine@bitbucket.org/jfine/python-argtools\\ abort: 'https://jfine@bitbucket.org/jfine/python-argtools' \\ does not appear to be an hg repository! }

}}
