git-daemon breakage in 1.5.4

I just noticed that my copy of git-daemon running from xinetd on Red Hat Enterprise Linux 3 has been broken since upgrading to 1.5.4.

On the client side this is what you see ("git clone" used in the example but you get the same issue with "git ls-remote"):

   git clone git://git.wincent.com/wikitext.git
   Initialized empty Git repository in /tmp/wikitext/.git/
   fatal: The remote end hung up unexpectedly
   fetch-pack from 'git://git.wincent.com/wikitext.git' failed.

Nothing printed to the logs on the server side: it simply hangs up. By connecting via telnet I've confirmed that git-daemon is running and does accept the initial connection.

The verdict according to "git bisect" is that 511707d42b3b3e57d9623493092590546ffeae80 is first bad commit:

     use only the $PATH for exec'ing git commands

     We need to correctly set up $PATH for non-c based git commands.
     Since we already do this, we can just use that $PATH and execvp,
     instead of looping over the paths with execve.

     This patch adds a setup_path() function to exec_cmd.c, which sets
     the $PATH order correctly for our search order. execv_git_cmd() is
     stripped down to setting up argv and calling execvp(). git.c's
     main() only only needs to call setup_path().

Does that look like it might be the issue? Anyone familiar with that part of the code care to comment? Any other info I can provide that might shed light on the problem?
