Thanks for that. Interestingly they were the same. Yea, for some
reason I have some very odd breakage happening there, and it behaves
differently running as root vs a non-root user. This is Gentoo running
Python 2.7.15.

Running it with python -v here's what I see failing when run as root:

# /usr/lib/python2.7/site-packages/MythTV/methodheap.pyc matches
/usr/lib/python2.7/site-packages/MythTV/methodheap.py
import MythTV.methodheap # precompiled from
/usr/lib/python2.7/site-packages/MythTV/methodheap.pyc
Traceback (most recent call last):
  File "find_orphans.py", line 221, in <module>
    DB = MythDB()
  File "/usr/lib/python2.7/site-packages/MythTV/database.py", line
1264, in __init__
    for tmpconfig in dbconfig.test(self.log):
  File "/usr/lib/python2.7/site-packages/MythTV/database.py", line 938, in test
    for conn in XMLConnection.fromUPNP(5.0):
  File "/usr/lib/python2.7/site-packages/MythTV/connections.py", line
607, in fromUPNP
    ip, port = reLOC.match(res['location']).group(1,2)
AttributeError: 'NoneType' object has no attribute 'group'

So it clearly doesn't like something in that methodheap.
Interestingly, run an a non-root user it gets past that but segfaults
later:

# /usr/lib/python2.7/site-packages/MythTV/methodheap.pyc matches
/usr/lib/python2.7/site-packages/MythTV/methodheap.py

/usr/lib/python2.7/site-packages/MySQLdb/constants/FLAG.pyc
Segmentation fault

Really odd one. Again, not all that important to me now, but strange.
Thanks again!
