It means git does not understand flag 0x40000000. Git 1.7.0.2 should understand that bit. I can only guess that "git pull" is from older version, or it ran a git command from older build. Do you have two versions of git on that machine?

You can turn off sparse checkout. That would remove all 0x4000000 flags, which makes the index compatible with old versions again:

cp .git/info/sparse-checkout sparse-checkout.saved echo '*' > .git/info/sparse-checkout git checkout

If it does not work, removing the index (.git/index) would do the trick.
