--- Comment #4 from Fabian Maurer dark.shadow4@web.de ---
I just tried to replicate the issue. Scrolling to the top and down again, sometimes several times resolves it for me.
Interesting, can't replicate that...
But even getting past this bug results in a error dialog upon clicking the final install button.
Please open yet another bugreport for this, and link it here.
