Yeah, if the URL doesn't even exist, you'd think that would be the
first error detected! What version of the Subversion client were you
running?

I just tried to reproduce this over http:// (didn't have an svn:// or
svn+ssh:// working copy at hand), but got a somewhat more reasonable
error message:

   $ svn info | grep URL
   URL: http://svn.collab.net/repos/svn/trunk/notes
   $ svn switch http://svn.collab.net/repos/svn/branches/1.4.x/notesTYPO/
   subversion/libsvn_ra_dav/util.c:1198: (apr_err=160005)
   svn: REPORT request failed on '/repos/svn/!svn/vcc/default'
   subversion/libsvn_ra_dav/util.c:630: (apr_err=160005)
   svn: Target path does not exist
   $

Still a bit cryptic, but at least in the right ballpark. This is with
trunk Subversion (i.e., 1.5-dev). I'll try setting up an svn://
repository and seeing if it gives the same error message with that...
