[TYPO3-mvc] $this->redirect preserve all existing parameters

[Muriel le Pair]

Hi,

I stumbled upon a bug in an extension. Because the extension automatic 
redirects a user that has already voted in the past with the flowing code:

$this->redirect('list', 'Question');


This will erase all other parameters from other extensions.

Is it somehow possible the preserve all existing parameters when using 
$this->redirect?
