Those are errors, yes, and they are coming from twisted.web2. In fact,
though, they aren't really errors in the sense of "something is broken".
The problem is that web2 is raising an error rather than just returning a
"Not Modified" response code. It is harmless, although I do find it
annoying myself.
Not sure what the fix would be; perhaps one of the web2 devs could opine
on that?
Hope this helps,
