We intermittently receive Internal Server Errors as UnreadablePostError reports from our instance (version 0.7.49).

We would really like to know the cause...

Traceback (most recent call last):

This issue *mostly* disappears by disabling Anonymous Questions / Answers by reducing the number of spam submissions to the answer page and (in turn) reducing the percentage of failed, interrupted postings. But doing this reduces functionality substantially. I would be useful to be able to disable the message, and require a captcha when posting anonymously . How can this be done?
