Meh, I forgot to install the icon (it was in the sources), should be fixed in the next upload.

The white window is an embedded browser, it should direct you to the login page, I actually tried to have a custom login window but it's against facebook's rules (since I could store the password that way...), if it's not working for some reason, try apt-get --reinstall install libqt4-webkit

About the name, it was actually called qtbook at the start, but facebook's policies don't allow "face" or "book" in the name so I had to go with something else.
