[copydeploymentfolders] Error 4 for QML projects

Whenever I try to compile a QML-project. Be it one of the sample ones or a custom one the error "[copydeploymentfolders] Error 4" appears.
I've seen the other bugs regarding that problem but none of the solutions (like upgrading to Creator 2.2 beta) helped.

This is the compile-log:
