Comment 1 Sebastian Dörner 2011-12-29 22:09:51 UTC 
I cannot reproduce this problem and I'm unsure what causes the segfault. Can you reproduce this reliably? It would also be useful to know your 

git --version

and the command line output of 

git branch -a

in the repository where the bug occurs.

Thanks.
Comment 2 michael 2011-12-30 17:53:22 UTC 
I'll try however I just realized I left out an important detail the original was converted from svn to git using git-svn. I have since rebuilt the repository using git only so the commits all have the correct e-mail/name associated. This was the result of an unrelated configuration issue on my part. I still have the original svn repository and try to recreate the issue using that. My current git version is 1.7.5.4. I don't know if this is the same as the one I had when I reported the issue.

Related issue: #295400 (different loc, but same thing in principle).
