In the status-quo, L824-825 checks:

                        if i < len_l and l[i] == ':':
                            res.second, res.microsecond = _parsems(l[i+1])

Avoiding an IndexError requires checking i+1 < len_l. This is easy to miss because the try/except catches IndexError. One way to trigger this is:

import dateutil.parser
dateutil.parser.IndexError = SyntaxError
dateutil.parser.parse('2017-07-17 06:21:', fuzzy=True)

Ugh, this giant try/catch block really has to go.
