It's a long time now since I came across this issue, but having just found
(and fixed) the problem I thought I should post an update.

Adding the print statements as suggested produced no output at all, so I
guessed that somehow the backend database just wasn't being accessed.

Trawling through the database 'settings' table I found that the required
entry of 'BackendServerIP' did not exist, but instead was an entry
'BackendServerAddr' with the correct IP address as data.

I have updated my 'find_orphans.py' script (lines 60 and 68 or
thereabouts), changing 'BackendServerIP' to 'BackendServerAddr' and the
script now works as expected.

I have absolutely no idea how this error has occured.
