We built a screensaver for Mac OS X called Screensaver Ninja. I'm not the main developer, but I did work a bit on it. Now, the screensaver is not starting on my machine. It works fine for everybody else but I'm at a loss about what's causing it to not start in my machine.
In the console, I'm seeing these messages:
2015-12-21 10:08:23.426 ScreenSaverEngine[2756]: <QCScreenSaverView: 0x7fd638d4dcc0>: Could not create patch from composition file "/Users/pupeno/Library/Containers/com.carouselapps.ScreensaverNinja/Data/Library/Screen Savers/Ninja.saver"

On machines in which the screensaver works, there's no trace of that message.
We used mostly Swift to build it, with a bit of Objective-C to handle a special case with cookies.
