+Running the prebuilt tarball build of git-annex, the bug does not occur.
+
+However, if I remove the git shipped with the prebuilt tarball, so it uses the system git, I do see the bug. So, it's apparently git version dependent.
+
+Also, I was able to reproduce it in a amd64 chroot. My other chroot was i386. Somehow architecture specific bug?
+
+---
+
+Instrumenting all calls to git to be logged with the full environment and command, I found this:
+
+<pre>
+GIT_INDEX_FILE='/home/foo/annex/.git/annex/index'
+--git-dir=/home/foo/annex/.git --work-tree=/home/foo/annex commit --quiet --allow-empty -m created repository
+</pre>
+
+This certianly looks like the index file setting for the git-annex branch is somehow leaking out past the branch commit operations. It continued setting that while setting up `gc.auto`; the next call to git after that stopped setting the index file.
+
+The only way I can see offhand this could possibly happen is due to an exception. It may be that on ubuntu an exception is thrown by code that runs a git command with the index file set, for whatever reason, and this causes the code that normally resets it back to not run.
+
+----
+
+Ok, found it! 
+
+<pre>
+\"withIndex entered\"
+
+*** Please tell me who you are.
+
+Run
+
+  git config --global user.email \"you@example.com\"
+  git config --global user.name \"Your Name\"
+
+to set your account's default identity.
+Omit --global to set the identity only in this repository.
+
+fatal: unable to auto-detect email address (got 'foo@darkstar.(none)')
+\"withIndex entered\"
+\"withIndex cleaned up\"
+</pre>
+
+Note lack of clean up after the first withIndex call. Thus leaving the environment passed to git polluted for further calls.
+
+This also explains why it's only happening on some systems, or with some versions of git. git's got all kinds of complexity around its username and email handling code.
+
+I have fixed this in git.

 This is a followup on [[bugs/internal_server_error:_unknown_UUID_on_webapp]]. In that issue, webapps previous to 20130929 would crash with `internal server error: unknown UUID`. This was fixed at that date, but some problems remain, namely that the remote that is recognized on the commandline doesn't show up in the webapp.
 
-`markov` is able to push to `marcos`, but not the reverse because `markov` is hidden behind a NAT. `git annex sync` seems to do the right thing accordingly on both ends.
+`markov` is able to push to `marcos`, but not the reverse because `markov` is hidden behind a NAT. `git annex sync` seems to do the right thing accordingly on both ends (which is: `marcos` doesn't try to push to `markov` but `markov` pushes to `marcos`).
 
 ### What steps will reproduce the problem?
