William asked me to post a bit more about what goes wrong. If you grab
the above tarball and drop it into the site-packages directory, you
should be able to run the notebook as usual. You'll notice some new bits
on the front notebook page -- those are translated strings that are
getting correctly pulled in via gettext. Log into the notebook as usual,
and you'll see the "sign out" string is also "translated".
The problem occurs when you try to print non-ascii text in a worksheet.
If you open a worksheet and execute a cell like
print 'Français'
the server either gets stuck in an infinite loop, or just won't render
the page. The traceback looks something like this:

line 1348, in set_output_text
self.__out = unicode(output)
exceptions.UnicodeDecodeError: 'ascii' codec can't decode byte 0xed in
position 1: ordinal not in range(128)
I've messed around in cell.py, trying to get all the strings to be
Unicode objects, but haven't met with any success. In the regular
notebook, I get no trouble with things like "print 'Français'", so
something about the gettext'ed code is wonky, but I'm not sure what.
If you want to work on this, the Sage tree in
/scratch/drake/sage-4.2.alpha0-x86_64-Linux on sage.math has my changes
in it.
Thanks for any help,
Dan
