w00t, I sent the xterm output to your mail.

But I forgot to mention that I had another problem:

In the dialog where I had to enter my Facebook credentials the submit button did not work for me. Ok, simply used the return button to submit the credentials...
But in the next page for the extended permissions the allow-button did also not work...
I checked the permissions for the NokiaN900 application on my FB profile. Both "Access my data, when I am not using the application" and "Publish content on my wall" are checked (permission descritions are translated by me, so they might look similar to you). Its not possible to give additional permissions to the application.

Dont know, but maybe its related to the problem that Facebrick shows nothing?
Are there permissions missing?
