This is a secondary error happening while trying to render the error page. We should probably try to avoid that. Could you please paste the traceback for the primary error (it should be in your trac.log, shortly before the traceback you provided).

Then again, I'd be surprised that uploading 800MB attachments would ever work, so we may not fix that.

Moved ticket assigned to next-stable-1.0.x since maintenance of 1.0.x is coming to a close. Please move the ticket back if it's critical to fix on 1.0.x.
