network data doesn't match template using JavaSVN over svn+ssh

I can access my repository via svn command line (svn+ssh://host/
path_to_repos) but when I try to add it to the repository explorer in
subclipse I get:

Error validating location:
"org.tigris.subversion.javahl.ClientException: network data doesn't
match template, expected (, read ? (65535)"

The interesting bit is that this exception seems to come from JavaHL
while I've got JavaSVN selected.

Mac OS X 10.4.2
Eclipse 3.1
