Strange.

I cherry picked 

        commit cc472cea1021dee90714703380a79e326aa0e681
        Author: Dan Williams <dcbw redhat com>
        Date:   Thu Jan 27 10:59:37 2011 -0600
        
            trivial: fix possible uninitialized variable usage

which seems to address the exact same issues. Do you know why I cannot
find the commit you referenced in any branch?

        $ git branch --contains cc472cea1021dee90714703380a79e326aa0e681
          master
        $ git branch --contains bbe547f7985498e0bc353ccd2e8e6f9a4a89249b
        $ git --version
        git version 1.7.5.1

I second that idea.
