Will try retesting on 5.1 dev to check my actual test target.
I don't think this has anything to do with the request I'm testing.

with PHP error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
no log entry with same test on new 5.1 dev and new 5.2.
NB I have not tried with earlier versions of Joomla (before 5.1)
