Scrollable View changes position on Device Rotation

[reverse-unina]

When I perform this sequence of events, the scrollable view on screen goes back to the top:

In the main activity:

1. Scroll Down
2. Orientation Change

@tibbi does not reproduce. But here's another problem: as soon as I open any child directory and rotate, it brings me back to the top directory. I'll create a new issue for that.

works fine already
