[James Bottomley]

Package: python-urllib3
Version: 1.24-1
Severity: important

Mythtv version 29.1+fixes20180821.gite5fc66e822-dmo2 is failing with

mythtv at vito:~$ /usr/share/mythtv/metadata/Television/ttvdb.py -B Superstore
Traceback (most recent call last):

ImportError: No module named ordered_dict

Meaning that mythtv can no longer pick up programme information from thetvdb.org

Falling back to version 1.22-1 makes everything work again.
