title: gitweb and gitolite cannot add new repo
body: <p>I installed gitolite first, and added some user and some repos, everything was fine. I then added gitweb, and could see repos through apache instance (just gitweb, no gitdaemon). The problem now comes in that I cannot add new repositories any more. Every time I pushed a change of gitolite-admin conf file, there were always 2 lines shown up in the log</p>
  
  <pre><code>remote: FATAL: git config 'gitweb.description' not allowed
  remote: check GIT_CONFIG_KEYS in the rc file
  </code></pre>
  
  <p>Despite these 2 annoying lines, the conf file is indeed changed every time. I tried to stop apache instance, but still no luck :-(</p>
  
  <p>I googled and cannot find any similar match to discuss this issue. Anyone can help? Thanks a lot!</p>
