Development server spins on an empty form post.

[Chris Beaven]

The relevant section from my template:

<form action="" method="post">
{% for followup in supplier.followups %}
<input type="checkbox" name="followups" value="{{ followup.id }}" /> {{ followup }}
{% endfor %}
</p>
<p><input type="submit" value="Remove selected logs" /></p>
</form>

If no checkboxes are selected, the servers sits there spinning after the submit button is pressed (which, note, has no name so isn't a POST item)

If I add <input type="hidden" name="empty" value="" /> inside the form, it works. So my conclusion is that the development server is spitting the dummy on an empty post.

When the next request comes in to the server, the console shows a traceback:

Just ran into this myself. The problem is in django.core.handlers.wsgi, in WSGIRequest._get_raw_post_data(), in the safe_copyfileobj() call.
