Upload obrazku prazdny tmpName

Ahoj. Mam nasledujici problem. Snazim se udelat upload obrazku pomoci formulare.

$form->addUpload('photo_1');

Dale to uploaduju na server:

$values = $form->getValues();
$name = $values['photo_1']->getSanitizedName();
$values['photo_1']->move(UPLOAD_DIR . '/' . $this->user->getId() . '/' . $name);

Vsechny fotky se tam normalne ukladaji, krome fotek z Canonu, ktere se neukladaji vubec a vypise mi to warning rename No error na radku v FileUpload.php:

if (!$func($this->tmpName, $dest)) {
  throw new Nette\InvalidStateException("Unable to move uploaded file '$this->tmpName' to '$dest'.");

Kdyz vypisu array values, tak mam u Canonu prazdny tmpName.

tmpName private => ""
error private => 1

Nevite, jestli by se dalo ten tmp nejak nastavit pred uploadem? Dekuji.
