Hi,

After updating from sage 4.6.1 to 4.6.2 I had trouble working with
sage-notebook because default imports were missing. This is what I
tried:

If I run sage-notebook, login and try to run a command as simple as

3;

I get a "NameError: name 'Integer' is not defined" error. If I run

from sage.rings.integer import Integer;
3;

everything works as expected. Also if I run sage -notebook (notice the
space) then executing the comand

3;

works. It's not a huge problem, but it kept me rebuilding sage and
python for a week. Any idea about why is this happening?

Best,
Marc.
