Working SVN repo

I'm starting a git repo to interact with a svn repo. The svn repository is set and working fine, with a single commit of a basic README file in it.

Checking it out works fine:

tchalvak:~/test/svn-test$ 
svn checkout --username=myUsernameHere http://www.url.to/project/here/charityweb/
A    charityweb/README
Checked out revision 1.

Failed git-svn clone of svn repo

When I try to clone the repository in git, the first step shows no errors...

tchalvak:~/test$ 
git svn clone -s --username=myUserNameHere http://www.url.to/project/here/charityweb/
Initialized empty Git repository in /home/tchalvak/test/charityweb/.git/
Authentication realm: <http://www.url.to/project/here:80> Charity Web
Password for 'myUserNameHere': 

...but results in a useless folder:

tchalvak:~/test$ ls
charityweb
tchalvak:~/test$ cd charityweb/
tchalvak:~/test/charityweb$ ls
tchalvak:~/test/charityweb$ ls -al

nothing to commit (create/copy files and use "git add" to track)
tchalvak:~/test/charityweb$ git fetch
fatal: Where do you want to fetch from today?
tchalvak:~/test/charityweb$ git rebase origin/master
fatal: bad revision 'HEAD'
fatal: Needed a single revision
invalid upstream origin/master
tchalvak:~/test/charityweb$ git log
fatal: bad default revision 'HEAD'

How do I get something I can commit back to? I expect I'm doing something wrong in this process, but what?
