[oe] [meta-oe] add-layers fails with python error

[Daniel F. Dickinson]

I'm not sure which list this belongs on, but since it's an attempt to 
use meta-oe that triggers the error, I post it here.  I've seen others 
reporting this issue prior to this, so perhaps it's related to the build 
environment?  (I'm on Debian 9).

Steps:

Checkout bitbake branch 1.34 (also occurs with 1.32 & 1.36)
Checkout oe-core master (also occurs with rocko)
Checkout meta-openembedded master (also occurs with rocko)

source oe-init-env

bitbake-layers add-layer /path/to/meta-openembedded/meta-oe

The follow traceback is shown:
