python -mtrace -t repro.py reveals a long string of these:
--- modulename: errors, funcname: __init__
errors.py(85): super().__init__(*args, **kw)
--- modulename: errors, funcname: __init__
errors.py(37): if line is not None:

_header_value_parser.py(858): return self
_header_value_parser.py(2429): value = value[1:]
_header_value_parser.py(2394): while value:

--- modulename: _header_value_parser, funcname: __init__
_header_value_parser.py(110): super().__init__(*args, **kw)
_header_value_parser.py(111): self.defects = []
_header_value_parser.py(2253): token, value = get_attribute(value)
--- modulename: _header_value_parser, funcname: get_attribute

_header_value_parser.py(2408):
mime_parameters.defects.append(errors.InvalidHeaderDefect(
_header_value_parser.py(2409): "parameter entry with no
content"))
... which would make sense as such, except at the end, the list of defects is
empty. And, of course, it should not take so long.
