[Bug] Segfault in git status

Hi all-

Somehow I've managed to create a repository that causes git status to segfault. To be honest, I'm not entirely sure how just yet. This comes after a weekend of splitting a repository into two separate repositories, filtering out a directory from one, and then creating grafts in those repositories to skip commits that now change nothing.

This was in OS X 10.5.2 with git compiled from cf5c51e. Falling back to 1.5.4.2 cleared it up, so with the help of git bisect I've narrowed the bug down to cf55870.

I'll spend some time this week trying to find the exact point in my filtering that git status went south and report back if I can replicate it in a more-controlled test.
