Xcode 4 Git—"This file does not exist at the requested revision"

[musicwind95]

Copied from StackOverflow, where no one has bothered to answer my question:

I have a local git repository that I set up with a project in Xcode 4. The repository shows up fine in the Organizer and I can see commit histories and Source Control icons in the File Navigator. Commits work fine as well. However, when I use the version editor, I get the error "This file does not exist at the requested revision" whenever I try to see any previous revision. I can't find any information on this error and have no idea how to fix. git log shows four recent commits (I know there are more, but I don't know if this is a restriction of the command or if something's disappearing). Any ideas on how to fix?

Bump? This is a rather pressing issue…

Are you sure your on a branch? Do a git status to check. This happened to me and it turned out i somehow wasn't on a branch.
