After adding a 'List Container' to a new page, I click on the configure (gear) icon to configure it... I get the following:

I also noticed (unless I am missing it) that if the 'load sample data' option is selected during install, there is no demonstration of 'List' capabilities on any of the sample content pages.
Is there a URL where I can see the list functionality actually working on the live demo site?

I have mentioned this once before that List Container is so simple WebPart that we didn't dedicate the whole sample page to it. So just place the list container WebPart on the page and add items to it. 

We are looking into the error you have reported and we will get back to you soon.

Regards
