Git-daemon messing up permissions for gitweb

I'm trying to set up a git repository for mainframe Linux developers to use at git390.osdl.marist.edu. Everything _seemed_ to go well, until Martin Schwidefsky started actually pushing changes back to the repository. When he does that, the projects disappear from the web page that gitweb.cgi is generating.

As far as I can tell, the problem is happening because these files are being written out with file permissions of 640, and since Apache is running as user wwwrun, it can't read them: -rw-r----- 1 sky git 5490 Jun 9 03:35 ./linux-2.6.git/info/refs -rw-r----- 1 sky git 54 Jun 9 03:35 ./linux-2.6.git/objects/info/packs -rw-r----- 1 sky git 41 Jun 9 03:35 ./linux-2.6.git/refs/heads/master -rw-r----- 1 sky git 41 Jun 9 03:35 ./linux-2.6.git/refs/heads/origin -rw-r----- 1 sky git 5490 Jun 9 04:00 ./s390-experimental.git/info/refs -rw-r----- 1 sky git 1 Jun 9 04:00 ./s390-experimental.git/objects/info/packs -rw-r----- 1 sky git 41 Jun 9 04:00 ./s390-experimental.git/refs/heads/master -rw-r----- 1 sky git 5490 Jun 9 11:31 ./s390-features.git/info/refs -rw-r----- 1 sky git 1 Jun 9 11:31 ./s390-features.git/objects/info/packs -rw-r----- 1 sky git 41 Jun 9 11:31 ./s390-features.git/refs/heads/master -rw-r----- 1 sky git 5490 Jun 9 03:41 ./s390-fixes.git/info/refs -rw-r----- 1 sky git 1 Jun 9 03:41 ./s390-fixes.git/objects/info/packs -rw-r----- 1 sky git 41 Jun 9 03:41 ./s390-fixes.git/refs/heads/master

I know I could brute-force this by adding wwwrun to the git group, but I first wanted to find out if that is the solution, or if something is wrong with the way I've set things up. I tried searching the mailing list archives, but nothing that appeared to be relevant turned up.

Thanks in advance for any help,
