Cloner Plugin got error 500, site partially cloned and can't delete

Hello, we tried to clone a site using the Cloner and pretty quickly got an error 500:

http://screencast.com/t/YMYXAUDc

We then tried to clone the same site again (to the same new url) and got "The blog already exists" http://screencast.com/t/kQamYETw4X.

So it looks like we have a site in a partially created state.

Is it possible to give you all access to our server so you can help us clean this up and then retry to clone the site to see if you can make it work.

I can share the details of the site privately.

Thanks!
Patrick
