title: Gitweb failure: fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/master
body: <p>I'm trying to use gitweb with a set of repositories that are managed with gitolite. We can successfully clone/push/pull from them over ssh with no problems. When I try to view the index page, I get the following errors in the apache log:</p>
  
  <p><code>fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/master, referer: http://gitwebbox/gitweb/?p=mlp2.git;a=summary</code></p>
  
  <p>I've run git fsck and it doesn't find any issues. The ref for master points to a hash that exists in the object tree.</p>
  
  <p>Can anybody help me figure out what is wrong? Thanks!</p>
