[IPython-dev] newest development version serves no notebooks

Hi all,

I have just pulled the latest version from github master, and it seems 
to me that notebooks are not served any more. When I try to open an 
existing notebook, I end up with a blank page. The same thing happens, 
if I create a new notebook on the dashboard. The notebook is created on 
disc, and as far as I see, it is a valid notebook, yet, in the browser, 
none of the components (toolbar, header, etc.) is loaded, and the first 
input cell is not even inserted. I started ipython from the command line 

 > BROWSER=google-chrome-stable ipython notebook

and here is my output:

"Creating new file" refers to the moments when I pressed "New notebook" 
in the dashboard, while the last two error messages were generated when 
I tried to navigate to the address of the notebook in firefox. Is there 
a reason why the kernel should not be started? In the dashboard, no 
kernels are listed as running. (command line ipython seems to be OK.) 
Oh, and I want to make clear that I cleared the cache of the browser:)

Is there something that I might have missed, or that I could use to 
track down the problem?
