Warning: array_merge(): Argument #1 is not an array in /Model/User.php on line 181

I'm getting this message since yesterday after logging in, I can't really tell why this shows up - but my hoster updated our PHP Version to 5.4.29 from an older 5.4.x version. Everything is working so far, I only get this warning. Does anybody else experience this with this PHP Version?

update your Doctrine version to the latest, or revert back to PHP 5.4.28.

PHP 5.4.29 introduced a BC break in the way serialize represents serializable classes, which broke Doctrine. Using the dev version of Doctrine fixes it.
