Error running 'git status' with Git version of current 'next' branch

Hi,

I'm getting the following error when calling 'git status' on one of
my projects.

git: dir.c:739: last_exclude_matching_from_list: Assertion `x->baselen
== 0 || x->base[x->baselen - 1] == '/'' failed.
Aborted (core dumped)

I'm using the current 'next', git version 2.0.1.664.g35b839c
I have bisected it to commit d3ccb7d (dir: remove PATH_MAX limitation).

Here's a simple script to reproduce it:

mkdir tmp
cd tmp
git init
mkdir -p foo/foooooooooo-bar/foooobar/foo/bar/foo/foobar/foooooooo/baaaaaar/fooooo
echo /foo >foo/.gitignore
git status
