No, this is due to the change made in 39ea6a4, in response to #746. Apparently I misunderstood how to do this with setuptools.

is it possible, that in the redis version the file is missing?

The workaround is to install pretalx via git, I'll release a bugfix release in a couple of days.

pip3 install --user -U "git+git://"

I tried the worksount out and got:

 sudo -u pretalx pip3 install --user -U "git+git://"
Collecting pretalx from git+git://
  Cloning git:// (to revision v1.2.0) to /tmp/pip-install-5jskn86f/pretalx
  Did not find branch or tag 'v1.2.0', assuming revision or ref.
error: Pfadspezifikation 'v1.2.0' stimmt mit keinen git-bekannten Dateien überein.
Command "git checkout -q v1.2.0" failed with error code 1 in /tmp/pip-install-5jskn86f/pretalx

is there something else to adjust?

Sorry, I meant v1.1.0 of course, since 1.2.0 is not out yet.

I just released v1.1.1 which should fix this issue.
