git-svn doesn't fetch anything

Hello

I have read access to a Subversion repo with standard layout at https://svn.turntool.com/svn/turntool/plantool

Using git version 1.6.1.2 I would like to use git-svn, so I do a clone:

$ git svn clone https://svn.turntool.com/svn/turntool/plantool -s
--username=harry
Initialized empty Git repository in /Users/h/work/projsvn/plantool/.git/

W: Ignoring error from SVN, path probably does not exist: (160013):
Filesystem has no item: '/svn/turntool/!svn/bc/100/plantool' path not
found
W: Do not be alarmed at the above message git-svn is just searching
aggressively for old history.
This may take a while on large repositories

I've been told that it is supposed to tell me a lot about fetched revisions, but there's nothing. And the directory is completely empty except for .git - here's my config:

$ cd plantool/
$ cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
        ignorecase = true
[svn-remote "svn"]
        url = https://svn.turntool.com/svn/turntool/plantool
        fetch = trunk:refs/remotes/trunk
        branches = plantool/branches/*:refs/remotes/*
        tags = plantool/tags/*:refs/remotes/

I would really like this to work, so if anybody has some pointers, please.
