[Python-modules-team] Bug#732679: test_nodes.ElementTests.test_empty fails for py3: "=?UTF-8?Q?=E2=80=A2?=" != "\\u2022"

Control: severity -1 serious

The bug makes the package FTBFS, so I bumped severity.

The last line should have probably been:

self.assertEqual(str(element), u'<Element mark="\u2022"/>')

...then it would be correctly converted to:

self.assertEqual(str(element), '<Element mark="\u2022"/>')

In the past it worked only by accident, due to a bug:
