I tried the same operation on the same VM instance using Firefox and everything 
went fine.
Then I retried with IE 9 and opened console to see if anything useful would 
show there.
This is the localized error message:

SCRIPT5007: Impossibile ottenere il valore della proprietà 'length': oggetto 
nullo o non definito 
index-bundle.js, Riga 57 Carattere 295

translation: can't get value of property 'length', object is null or undefined.

Well, installing Google Chrome Frame plugin for IE fixes the problem, but I'm 
not sure if, from the Google Refine developers point of view, this 
configuration has to be considered mandatory or just a workaround.
You might just mention it in the installation doc.

Did you not get prompted to install the Chrome Frame plugin the first time 
Google Refine opened in IE?  That's what happened with my IE 9 installation.

Sure it prompted, but I didn't install it on the first time because I didn't 
find anywhere a statement saying I should install a Google Chrome related 
software upon Internet Explorer to make Refine work.
I think the shown message is misleading because tells about how to improve your 
web experience with Chrome technology and not that you actually need it to use 
the page.
Maybe this is obvious for the developer who added the tag, but not for the 
common user.
Secondly I don't see the point in the Google strategy piggybacking Internet 
Explorer deficiencies with Chrome technology.
I looked at the installation directories of Chrome Frame and it seems that the 
occupation is roughly equivalent to a standard Chrome installation, and this 
probably means that you when installing Chrome Frame are actually installing 
Chrome, even though not fully enabled.
From the Chrome Frame FAQ I understand that it slips in replacing the rendering 
and the js engines when directed by a tag.
I think among many other people, especially web developers, that IE is inferior 
compared to the other browsers, and in fact I don't use it, but if the IE 
support means using Chrome in the shadow, well, why should I use IE at all?

OK, we'll look at making it clearer to the user that the Chrome Frame plugin is 
mandatory for Refine. It's also possible that IE 9 has improved enough over IE 
7 & 8 that the Chrome Frame isn't really needed for that release.

The reason for not just telling people to use a different browser is that in 
many corporate environments users don't have a choice.  The use of Chrome Frame 
is a low cost way for the Refine team to support these users without having to 
implement extensive workarounds.
