I looked at the 1.5.4 container.py file and lines 10 to 15 read:

import os, posixpath, sys, re, urllib

from lxml import etree
from lxml.etree import XMLSyntaxError
from urlparse import urldefrag, urlparse, urlunparse
from urllib import unquote as urlunquote

while the 1.5.3 container.py file has:

import six
from six.moves import range
from polyglot.builtins import unicode_type

__license__   = 'GPL v3'
__copyright__ = '2011, Grant Drake <grant.drake@gmail.com>'
__docformat__ = 'restructuredtext en'

import os, posixpath, sys, re
import six.moves.urllib.request, six.moves.urllib.parse, six.moves.urllib.error
from io import open

from lxml import etree
from lxml.etree import XMLSyntaxError
from six.moves.urllib.parse import urldefrag, urlparse, urlunparse
from six.moves.urllib.parse import unquote as urlunquote

I copied the segment from the 1.5.3 container.py into the 1.5.4 container.py and now I get a different error message. I tried 4 or 5 single options and the same error.

Spoiler:

calibre, version 5.0.1
