I have now changed my nginx config as follows:

server {
     listen   80;
     server_name svn.domain.com;

     location / {
         set $dest $http_destination;
         if ($http_destination ~ "^http://svn.domain.com/(.+)") {
             set $dest http://localhost:81/$1;
         }

         proxy_set_header Destination $dest;

         proxy_pass http://localhost:81;
     }
}

Now the COPY Request looks as follows (captured with tcpdump):
COPY /tourvital/!svn/bc/120/trunk HTTP/1.0
Destination: 
http://localhost:81/tourvital/!svn/wrk/0200ab05-2301-0010-93d2-4be8b1bacda6/branches/test
Host: localhost:81

Shouldn't this be working?
