There is a bug here:

nette/Nette/Application/Application.php

Lines 166 to 168 in 0474caf

if (!$this->httpResponse->isSent()) {
$this->httpResponse->setCode($e instanceof BadRequestException ? ($e->getCode() ?: 404) : 500);
}

The check if (!$this->httpResponse->isSent()) { is not enough to know that it is possible to send a header (or set HTTP code in this case). It can still throw this error:

nette/Nette/Http/Response.php

Line 315 in 0474caf

trigger_error('Possible problem: you are sending a HTTP header while already having some data in output buffer. Try OutputDebugger or start session earlier.', E_USER_NOTICE);
.
