Change Details

Unfortunately, this doesn't seem to completely fix my problem (I am still getting `Unknown commit` exceptions). But it does seem to help.

For at least one of our repositories, this patch fixes the `Unknown commit` exception. Unfortunately, it doesn't seem to completely solve this problem though, but I suspect that this is due to commits that were overwritten with a `git push --force` or similar.
