This is a tdeio_subversion. It allows you to browse a (remote) Subversion repository. 
The expected URLs are something like : svn+http://svn.collab.net/repos/svn
This will show you the current HEAD version of the repository (just like the one you would get 
with http://svn.collab.net/repos/svn). 
You can also try : svn+http://svn.collab.net/repos/svn?rev=500 so that it displays the revision 500.
