Xqt made gerrit:178796 https://gerrit.wikimedia.org/r/178796/ not depend on gerrit:179591 https://gerrit.wikimedia.org/r/179591/ anymore. The latter should be merged, or the former should be reverted, because of failing tests https://travis-ci.org/wikimedia/pywikibot-core/jobs/44055432. I remember this already happened some time ago. Please do not remove dependencies from Gerrit changes without accurate checks.
