I tried all git releases from 1.5.3 to 1.5.3.4 as well as the current
master and all of them crashed. A small shell script to reproduce the
problem is attached.

Manual bisect? Ugh. This *is* the century of the competent developer
tools, you know... ;-)

Then, how do I search for a good version with git bisect if I only have
the one data-point "master is bad"?

AFAIK Junio introduced the option to start with just a bad commit, and no 
known "good" one.

Yep, just found it.  Since v1.5.2-rc0~77^2(git-bisect: allow bisecting 
with only one bad commit.) it is supported.

From the commit message:

    This allows you to say:

        git bisect start
        git bisect bad $bad
        git bisect next

OK, using that approach, I bisected it, and even found a "guilty"
commit, although it is pretty much useless:

1cfe77333f274c9ba9879c2eb61057a790eb050f is first bad commit

    git-blame: no rev means start from the working tree file.

    Warning: this changes the semantics.

    This makes "git blame" without any positive rev to start digging
    from the working tree copy, which is made into a fake commit
    whose sole parent is the HEAD.

    It also adds --contents <file> option to pretend as if the
    working tree copy has the contents of the named file.  You can
    use '-' to make the command read from the standard input.

    If you want the command to start annotating from the HEAD
    commit, you need to explicitly give HEAD parameter.

I don't know if it is in the documentation (I rarely read it), so if it is 
missing, it would be nice if you could add the description there.

Nothing in there yet AFAICT. Will try to get a patch done tomorrow.

thanks,
