Unable to checkout a particular SVN revision

I'm trying to clone a specific SVN revision with git-svn:

    git svn clone -r 12345 https://host/svn/foo/branches/bar xyz

but it doesn't check out any files, I see just this:

    Initialized empty Git repository in /Users/liyanage/Desktop/xyz/.git

If I try the same thing with SVN like this:

    svn co -r 12345 https://host/svn/foo/branches/bar xyz
    
then I get what I expect, it checks out all the files and "svn info" gives me this revision.

I think it's because this particular revision wasn't committed on this branch, i.e. it doesn't show up in "svn log". If I try a revision that is listed in the log, it works as expected.

Is there a way to make this work?
