[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [53955] trunk/blender/source/blender/ python/intern/bpy_app_translations.c: Print warnings when invalid py dict/ key/value is found in translations data (do not error here, this is not critical and can be ignored/skiped, and it would break translations for other addons as well).
