Configuration of git-http-backend with Nginx (returning PROPFIND 405)

Question

I'm trying to configure git-http-backend over nginx and having some troubles.

The actual result is that I'm getting a 405 error for the PROPFIND request:

192.168.1.45 - - [22/Feb/2015:16:50:46 +0100] "GET /lw/bla.git/info/refs?service=git-receive-pack HTTP/1.1" 200 0 "-" "git/2.3.0" "-"
192.168.1.45 - - [22/Feb/2015:16:50:46 +0100] "GET /lw/bla.git/HEAD HTTP/1.1" 200 23 "-" "git/2.3.0" "-"
192.168.1.45 - - [22/Feb/2015:16:50:46 +0100] "PROPFIND /lw/bla.git/ HTTP/1.1" 405 172 "-" "git/2.3.0" "-"

Versions:

Debian GNU/Linux 7.8 (wheezy)
git version 2.3.0
nginx version: nginx/1.6.2
fcgiwrap version 1.0.3

The configuration parts:

I think that the request is not served using the smart http-backend. But I couldn't identify the reason.

Anyone who has a clue what is wrong with my configuration?

thanks in advance.

Oh sorry, this was my mistake.

The problem with my configuration was, that I clone the repository via https_://dlock.../lw/bla which successfully worked, because of:

location / {
  root  /var/git;
}

But location ~ /git(/.*) { expects for sure: https_://dloc.../git/lw/bla to serve requests via smart http backend m(.

If anyone stumbles upon same issue, the following config is working for me (with cgit):

server {
   listen 443;
   server_name git.dloc.com;
   access_log /var/log/nginx/git.dloc.access.log main;
   error_log /var/log/nginx/git.dloc.error.log;

   ssl                 on;
   ssl_certificate     /etc/ssl/dloc/dloc.crt;
   ssl_certificate_key /etc/ssl/dloc/dloc.key;

   auth_basic "Login";
   auth_basic_user_file /etc/apache2/passwd/git.pwd;
   location ~ /\. { deny  all; }

   location ~ /git(.*) {
      include /etc/nginx/fastcgi_params;
      fastcgi_param SCRIPT_FILENAME /usr/local/libexec/git-core/git-http-backend;
      fastcgi_param GIT_HTTP_EXPORT_ALL "";
      fastcgi_param GIT_PROJECT_ROOT /var/git;
      fastcgi_param PATH_INFO $1;
      fastcgi_pass      unix:/var/run/cgit-fastcgi/cgit-fastcgi.socket;
   }

   try_files $uri @cgit;

   # Serve static files
   location ~* ^.+\.(css|png|ico)$ {
      root /var/www/cgit;
      expires 30d;
   }

   location @cgit {
     include fastcgi_params;
     fastcgi_param       SCRIPT_FILENAME /var/www/cgit/cgit.cgi;
     fastcgi_pass        unix:/var/run/cgit-fastcgi/cgit-fastcgi.socket;
     fastcgi_param HTTP_HOST $server_name;
     fastcgi_param PATH_INFO $uri;
     fastcgi_param QUERY_INFO $uri;
  }
}
