Strange bug on MacOSX - can anyone reproduce?

Hi!

I've a very strange bug on MacOSX 10.5 on a case sensitive HFS+ filesystem.

git very regular show the following behavior:

git op fails with an "error: Unable to append to $(FILE)" message, a "cat $(FILE)" and the same git op solves the problem deterministically.

Here is an example:

rlezuo@rlezuo:~/Projects/XXX/documentation$ git pull
remote: Counting objects: 100, done.
remote: Compressing objects: 100% (74/74), done.
remote: Total 74 (delta 59), reused 0 (delta 0)
Unpacking objects: 100% (74/74), done.

can anyone reproduce this? Is this a git bug or is this a OSX bug?
