I also see it....didn't bisect it yet since I was in a rush and had a 
simple work around. I was doing a git pull between two repositories on a 
NFS 4 w/krb5 security. Got the error about .git/objects/pack (error: 
unable to open object pack directory: .git/objects/pack: Is a 
directory). If I then run 'ls .git/objects/pack', and then the 'git 
pull' again it works.
