raise.exc.HTTPFound() in BaseController.redirect() results in pyramid_debugtoolbar error.

This is taken from example "04-applied-web/final_4_blue_yellow_app" and shows up in the console after attempting a valid "Register" of a new user.

This seems to be related to recent bugs reported at:

• Pylons/pyramid_debugtoolbar#319
• Pylons/pyramid_debugtoolbar#320
  The former seems similar to the problem here. The latter seems to be the root cause and a merged fix. One of the comments on the former is: "We don't recommend raising HTTPFound unless it truly is an exception..." Oh? It seems like this was fixed in pyramid-debugtoolbar 4.3? I have that version, but the problem persists.

Below is the trace I see on the console (with my home directory slightly doctored):

Hey, It's annoying that Pyramid doesn't "eat" that exception but rather reports it as a failure. There is nothing wrong with the code however. Just ignore it in the console. Best, Michael

Thanks, Michael. Wasn't sure if I had a Pyramid bug that was going to stop me, or if there was a recommended alternate style.
