Say, you have some model, which `__str__` uses
`django.utils.formats.date_format` with custom format string.
`settings.FORMAT_MODULE_PATH` contains module, in which this string is
defined.
So, when you create object of this model via admin interface, the
following things happen:
1. Django calls `construct_change_message` to create LogEntry, which is
decorated with `@translation_override(None)`, which will deactivate
current language
2. To write object representation with custom format in change message,
`django.utils.formats.get_format` will be called
3. `get_format` will try to find custom format, but it can't be done when
active language is None, so original string will be returned as-is
4. `django.utils.dateformat.format` will interpret custom format string
literally, which may not fail with exception, but will be totally wrong
anyway
