Sorry, I did not read your message carefully enough.

Nevertheless, even if Klein isn't at fault, it's the "top layer" here, so a bug should be reported there.  If we need to file a bug in Twisted too, having the Klein bug to link to for reference will be good as a practical example of the need for the fix :-).

I also tend to assume that other people are like me, and will forget to write a bug and the bug will get lost, so a lot of my immediate replies end up being "file it file it file it" ;-).  So it's good, just to quash that impulse of _mine_ if for no other reason, to start by filing a bug so it won't get lost, then start the mailing list thread by linking to the bug to prompt some action on it...

For what it's worth, Klein isn't wrong to use processingFailed, because it doesn't start with a "_".  Twisted is wrong for not documenting it :-).
