I can pretty consistently crash 24.0.95.1 (and could some previous
pre-releases).

Since I am on Windows, I'm not sure how to help debug this.  How can I
generate a useful stack trace for this?

The step that crashes is to add a new file to egg (the emacs git interface).

The steps to reproduce are:
 * Create an empty repository.
 * Create file1, add, and commit with our without egg.
 * Create 2 new files.
 * Run egg-status on the directory which will show 2 untracked files.
 * Put the cursor on the first untracked file and press 's' to stage it.

After the crash, the file is staged, so the error is probably during the
refresh of the status, but I am not sure.

Is there anything else I can do to test this?

I'm using msysgit: git version 1.7.7.msysgit.1

I am an admin on this box.

The information from report-emacs-bug (which I can't use because I can't
send email from it) is below.  Note that the recent input is not useful
since this is a new instance.
