Hi! Recently I started to see new warnings from Python when building core:

    zipfile.py:1517: UserWarning: Duplicate name: 'cmd/ar/sc_bulletsandnumberingdialog.png'

They have been introduced by commit a8c3addfce4df0fa8278d83764148d4aec40b36e. IMO, it looks natural (?) to treat Python warnings as errors when we use --enable-werror. Having that would prevent introduction of new warnings like that. So I have prepared https://gerrit.libreoffice.org/c/core/+/100268 to do that. The change allows overriding it in a particular build, e.g. calling `PYTHONWARNINGS=default make`. Please comment if this is OK, or is a bad idea. Thanks! -- Best regards, Mike Kaganski
