Done.

Format diff is one click away, "raw". You want me to use the web to
file bugreports, so I thought you would be confortable with web reports too ;)

That's nicer, I'll fix that thanks!

It's a design decision, I want twisted to never generate exceptions,
unless there's a bug in twisted. An exception showing up in the log must
be like a kernel oops, when it happens it must signal a bug.

I considered logging a message but I thought it was not worth it, but
OTOH given this is still code under development, you're probably right
that it's a good idea (so if it happens too often we may want to review
the code).

My code work right, SVN didn't, so don't blame on me for fixing bugs
please. It's only a style error, not anything that could harm the
runtime. But I agree in making it more eye candy.
