After I close\nthe editor it just hangs. and I have to Ctrl-C to get it to go. I\nsuppose it could be an issue with vim or similar.\n\nI never noticed the problem with the same setup when I wasn't using\nthe next branch. Tomorrow I will have some time to try out the 2.5.x\ntag and maybe see if I can bisect if it doesn't have an issue. I can\ntry 3-4 rebase interactive attempts it usually shows up pretty fast.\nWhat bothers me is that it's not 100% reproducible.\n\nI'll follow up with more detail tomorrow.\n\nRegards,\nJake\n"},{"id":"271206","messageId":"vpq37xopjwh.fsf@grenoble-inp.fr","threadId":"40493","inReplyTo":"CA+P7+xqMFFtVPnZ7Pw9B9oYXHe5N=Ectyd-M+_aGb2NKjRvLAg@mail.gmail.com","subject":"Re: git interactive rebase bug?","fromName":"Matthieu Moy","fromEmail":"matthieu.moy@grenoble-inp.fr","sentAt":"2015-10-06T06:53:50Z","receivedAt":"2015-10-06T06:53:50Z","isPatch":false,"sender":{"key":"matthieu.moy@grenoble-inp.fr","avatar":"https://gravatar.com/avatar/72c8a2705971a25dfaff23cece15130d405685845d911aedd5667ace277f3fc5?d=mp&s=160"},"body":"Jacob Keller writes:\n\n> I've been experiencing a very annoying bug when performing interactive\n> rebases.

It did hang one time\nfor about 15-20 seconds and then worked, and suddenly no longer has\nissues... I'll try to remember these two tricks incase it does hang\nagain and I'll report what I find.\n\nThanks,\nJake\n"}]}
