--- Comment #10 from Jan Essert netz@lytenyn.de --- OK, I managed to disable the automatic 301 redirection for wpad.dat, and now the installation works like a charm.
I am really sorry if I chased you into a rabbit hole there and if this is incorrect configuration on my side.
It may still be a bug, though, since it crashes, so I would prefer to leave it to you whether to close it or not.
I can also provide additional data, of course.
