reopen #8853 against 2.2 branch

When the exception message contains some HTML, this display is
broken.

I don't know enought about the differents Output classes.
Maybe we have to check the current Output class before
escaping. But for the moment, we allways format the message
with error tags, so I guess the escape is not an issue.
