Thanks for the update!

It's more than that the bot has been disabled - were it just disabled, I
wouldn't have seen it, nor written that email. The bot has been red and
prone to (though not always - as Renato's pointed out, a red bot that
remains red may not send email, but purple (exception)->red (even if it
were red before the exceptional result) does send email) send email on some
of its failures, which adds noise to the system and makes it hard for
developers to trust/act on buildbot results.

Is there any reason the test couldn't've been XFAIL'd from the start, while
investigation continued?
