3420	"Twisted web Resources should ""return ErrorPage"" instead of  ""raise WebError"""	sajith	sajith	"In case of errors, twisted.web `Resource` instances should be responding with an error page, instead of throwing an exception.  Any `raise WebError` instances we have in Tahoe WUI should be replaced with `return ErrorPage`.
