Ok, I re-installed everything via direct-download and I still have the same problem.

I scooped the internet and apparently it's qgtkstyle that can't detect my current GTK theme. Unfortunatly, I have found no answers. So my question is, on what does qgtkstyle depend on to find my current gtk theme? When I know that, I can take steps to solve the issue.

So, any qt dev who knows this?
