Things worked fine. Looked at\nrefs.c:try_remove_empty_parents() as well. Still could not find any\nbug there.. So no good news. I don't suppose that if you run \"git gc\"\nagain, it would remove $GIT_DIR/refs one more time?\n-- \nDuy\n"},{"id":"247610","messageId":"1407859882.17965.1.camel@spirit","threadId":"37332","inReplyTo":"CACZXET_qPzBtqJLXBbou+iZ_Muj=VqCBe5qMADN72VScsuHRVQ@mail.gmail.com","subject":"Re: Error \"fatal: not a git repository\" after auto packing","fromName":"Dennis Kaarsemaker","fromEmail":"dennis@kaarsemaker.net","sentAt":"2014-08-12T16:11:22Z","receivedAt":"2014-08-12T16:11:22Z","isPatch":false,"sender":{"key":"dennis@kaarsemaker.net","avatar":"https://avatars.githubusercontent.com/u/200649?v=4"},"body":"On ma, 2014-08-11 at 18:56 -0400, Luke Campagnola wrote:\n> \n> raven:/home/luke/vispy (transform-cache)$ git checkout master\n> Switched to branch 'master'\n> Deleted 103 .pyc files\n> Deleted 11 empty directories\n\nThis looks like you have a local post-checkout hook that deletes empty\ndirectories.
