[boost] [Trac] Catch-22: Captcha Errors on legitimate submissions

I had a ticket attachment and comment both rejected from a "captcha error," so I decided to open a Trac ticket on the captcha mechanism itself. But guess what? THAT ticket was also rejected by the captcha error. Catch-22! So I'm posting it here. I get: -------------------------------- Captcha Error Submission rejected as potential spam (StopForumSpam says this is spam (username)) Trac thinks your submission might be Spam. To prove otherwise please provide a response to the following. -------------------------------- But there's nothing following to which to provide a response. Is it mis-configured?
