E.g. try to retrieve https://bazaar.launchpad.net/~brz/brz/trunk/changes/info results in a 500 -- https://code.launchpad.net/~jelmer/launchpad/+git/launchpad/+merge/435608 Your team Launchpad code reviewers is requested to review the proposed merge of ~jelmer/launchpad:public-https into launchpad:master. _______________________________________________ Mailing list: https://launchpad.net/~launchpad-reviewers Post to : launchpad-reviewers@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-reviewers More help : https://help.launchpad.net/ListHelp
