It seems that by default multibranch-pipeline and git-review setup does not discover any branches in gerrit projects, even after adding "Filter by name (with wildcards)" with defaults settings (include *, exclude: <empty string>) — which seems to have no effect.
Once we add "Discover open changes" to the config, Jenkins starts to discover open branches on gerrit....but detection seems to be buggy because I see some failures in the logs:

The sample project I used for testing is https://review.gerrithub.io/pycontribs/powertape (configured with the same URL.).
A Jenkins instance with test jobs already configured is accessible at https://j.sbarnea.com/job/test-jjb-multibranch-gerrit-http-ano/configure – If you need access to it just mention your github login in a comment.
