First of all a big thanks to you John for your help in this matter. It is very much appreciated. 🙂
I followed your advice and booted in safe mode, but nothing changed. The gestures don't work in Finder.
Besides, I am not sure whether it is a third party application that causes this trouble since Finder is the only affected app. As you write yourself, a third party application would influence gestures in general, so every app would show this error.
Nevertheless I ran the suggested software and here is the output.
