OK

Looks like the configparser subclass recognises that a config file has already been read (by a previous test) and so, in a broken attempt to prevent unnecessarily parsing "the" file repeatedly, silently declines to parse any further files.

(This bug relates to the use of singleton-pattern and the pervasively-widespread argument-passing of the config-filename. In other words, implicit dependence upon mutable global state. See also issue #68 and #65.)

Fixed (without attacking broader issues) in commit 53733c1, merged in v2.1.3.
