Oh, i didn't realize you were trying to check out a tag... In that case
the commands you gave were correct. I could successfully run your commands
here (though i have no idea if the file you talk about is up to date or not).

It's probably worth trying a newer version of git, could be a bug I guess.
Given the error message you could also try first checking out a branch, and
then the tag. ie git checkout -b master linus/master; git checkout tip-foo
It could also be that the tag just doesn't point to the commit you expect..
