Thanks for the quick reply, Ingo. Tried your suggestion (see below, but no

Added a file src/filter/autotests/gpghome/gpg.conf, with the line
allow-weak-key-signatures
also made sure by debug logging it gets deployed to the temporary GNUPGHOME 
working dir with all the other files by GPGHelper,
but test keeps failing with same error :(
