I just created various setuptools projects (Different Python version, with and without main file) on Linux on latest contrib which include the Important files patches, NetBeans is build from the 8.2 branch and cannot reproduce.

Can you or is this solved?

The descriped Problems cannot be reproduced, so I removed File-Listening and replaced it with an explicit update Action
