OK, thanks.  It seems we're not the only ones with unicode problems then...

I just closed the ticket with this comment, so we can forget about it:

"""
As pointed out by Ville on list, this is really a pprint bug, possibly
unicode-related.  Since pprint is part of the stdlib, I'll just close
the bug as 'invalid' for now.

If someone comes up with an idea on what to do with pprint in the
stdlib, it should then be reported on the python.org tracker.
"""

I still wonder what exactly causes it, but I don't have the time or
interest to go spelunking inside pprint to find out.

Cheers,
