Hello Greg, thank you for your answer. I have checked it twice and the file is really empty. I even opened it with a hex editor - no content. BUT in order to create a bug ticket I tried to make a mcve and I didn't succeed. I copied the function (load_plugins) 1 to 1, but outside my program it works as it should. So it seems that something inside my application is causing this problem. Hmm ... Fortunately this is a pure python application so debugging should lead to enlightenment. :-)
