Re: [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.

I have the same problem, also on OS X.

Vienna:Project pieter$ git --version
git version 1.5.4.2.263.g5729

which is 'next' + 2 patches

This happens in at least one repository, most others are just fine.
