Svn – Subversion: Secure connection truncated

I'm trying to set-up a subversion server with apache2/webdav access. I've created the repository and configure Apache according to the official book, and I can see the repository in a webbrowser.

The browser shows:

conf/
db/
hooks/
locks/

Although clicking any of those links gives an empty xml document like:

<D:error>
<C:error/>
<m:human-readable errcode="2">
Could not open the requested SVN filesystem
</m:human-readable>
</D:error>

I've never used subversion before so I assume this is correct?

Anyway, when I try to connect via a command line client, it asks for my password, I give it, then I get the (useless) error message:

svn: OPTIONS of 'https://svn.mysite.com': Could not read status line:
Secure connection truncated (https://svn.mysite.com)

Or with SSL turned off:

Could not read status line: connection was closed by server

The command I'm using is:

svn checkout https://svn.mysite.com/ svn.mysite.com

Subversion was installed using Ubuntu's package manager. It's version 1.6.6 on Ubuntu 10.04.
