Emitted when processing has failed for a message; this
could mean either that it could not be read (if
#SoupServer::request_read has not been emitted for it yet),
or that the response could not be written back (if
#SoupServer::request_read has been emitted but
#SoupServer::request_finished has not been).
@message is in an undefined state when this signal is
emitted; the signal exists primarily to allow the server to
free any state that it may have allocated in
#SoupServer::request_started.
