iterparse cannot load entity definitions from local dtd file

$python ./iterparse_bug.py
Python : sys.version_info(major=2, minor=7, micro=9, releaselevel='final', serial=0)

lxml.etree.XMLSyntaxError: Entity 'bar' not defined, line 4, column 14

The python script, the xml and the dtd are attached. Since those files are really simple, I'll also briefly show their contents here.

The main part of the python script looks like:

context = etree.iterparse("foo.xml",load_dtd=True)
for action, elem in context:
    print("%s: %s" % (action, elem.tag))

The xml file is:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE foo SYSTEM "foo.dtd">
<root>
  <leaf>&bar;</leaf>
</root>

The dtd file is:
<!ELEMENT root (leaf)*>
<!ELEMENT leaf (#PCDATA)>
<!ENTITY bar "&#246;" >

I've tried to validate the xml with xmllint (xmllint --dtdvalid foo.dtd --noout foo.xml), and it was successful.
Also, when I use the following python code

import lxml.etree as etree
parser = etree.XMLParser(load_dtd=True)
etree.parse("foo.xml",parser)

it was also successful.

So it seems that the problem is with the iterparse function.

Does "Fix released" mean that you found a version (3.6?) in which this is fixed? Can this ticket be closed then?

Ah, sorry. Was confused. Yes, it's obviously fixed in 3.6.1.
