You might get the above error message when cloning certain git repositories (for example the rails repository). It indicates that there is a malformed timestamp in some commit, and your git installation is configured to validate it.
As a workaround, you can disable the validation using
git config --global fetch.fsckobjects false
This settings seems to be the default for most git installations anyways.
