Testing against a gerrit 2.16.4 based server, the git-review version 1.2.5 fails when running `git review -l`, though most other operations work correctly. Version 1.2.6 of git review will report deprecation warnings about topic encodings when pushing up a review to gerrit 2.16.4, but works correctly. Version 1.2.7, which is available in TumbleWeed doesn't exhibit any problems in my limited testing.
