Error running update using trunk

I have a working copy created like this:

$ svn co --depth=immediates http://svn.apache.org/repos/asf/subversion
$ svn up --set-depth=infinity subversion/trunk
$ svn up --set-depth=immediates subversion/branches
$ svn up --set-depth=infinity subversion/branches/fsfs-format7

This all worked fine. But when I tried to expand another folder, I
get an error:

$ svn up --set-depth=infinity subversion/branches/ev2-export
