cppunitTest fail on .. language tags(?)

Hi,

jenkins fails on
 https://gerrit.libreoffice.org/#/c/66169/
with
 
https://ci.libreoffice.org/job/gerrit_linux_gcc_release/23586/consoleFull#547894439d893063f-7f3d-4b7e-b56f-4e0f225817cd

did an additional build, that fails in test_languagetag. (see below)
I remember with initially committing there was a warning on language
tags, which I suppressed with --no-verify ..

Hints & other help appreciated.
