v1.021 Exception in HTTP response re-managed

An exception that was happening... still happens.

Now it should be corrected (but still, it's impossible to reproduce) thanks to the http.client.IncompleteRead exception.

Here was the trace :

    data = response.read()
  File "/usr/lib/python3.10/http/client.py", line 460, in read
    return self._read_chunked(amt)
  File "/usr/lib/python3.10/http/client.py", line 598, in _read_chunked
    raise IncompleteRead(b''.join(value))
http.client.IncompleteRead: IncompleteRead(0 bytes read)
