Weird. I have never heard of anything like it.

Some things off the top of my head: Does your GIT_AUTHOR_NAME or
GIT_AUTHOR_EMAIL contain any odd characters that might confuse a parser?
Do you do anything special with setting up those environment variables
in your shell (e.g., in a .bashrc or .profile; those files _shouldn't_
be read by a non-interactive shell, but it's something to investigate)?
For that matter, how do you set up your identity in general (by
environment, or in ~/.gitconfig, or a local .git/config in each repo),
and what does it contain?

Can you try running this in a repo that's giving you problems:

  . git-sh-setup
  git log --format=%H --author=your.name |
  while read rev; do
    get_author_ident_from_commit $rev
    git format-patch -1 --stdout $rev |
      git mailinfo /dev/null /dev/null
  done | less

and check that the output looks sane? I want to make sure there's
nothing in your commits that is confusing our parser.

If that doesn't turn up anything, I think the next thing to try would be
making a script that reproduces the problem for you, and see if I can
reproduce it here.
