[New-bugs-announce] [issue28981] distutils/check.py overzealous catch block hides errors

[Matt Bogosian]

New submission from Matt Bogosian:

>From (e.g) https://github.com/python/cpython/blob/2.7/Lib/distutils/command/check.py#L145:

{{{
        try:
            parser.parse(data, document)
        except AttributeError as e:  # <- this could happen anywhere inside parser.parse
            reporter.messages.append(
(-1, 'Could not finish the parsing: %s.' % e, '', {}))
}}}

Without a stack trace, diagnosing problems like #23063 becomes unnecessarily difficult. See also:

* https://sourceforge.net/p/docutils/bugs/270/
* https://sourceforge.net/p/docutils/bugs/302/

I'd offer a patch, but I'm not sure what is meant to be signaled by the `AttributeError`. (Could `parser.parse` not exist? Is it something else?)
