Estou muito atrasado para essa festa, mas enfrentei o mesmo problema. Eu tinha acabado de migrar de uma versão mais antiga do svn para uma mais nova e de um servidor mais novo. Os diretórios de trabalho locais ainda estavam apontando para o servidor antigo. O comando relocate do svn corrigiu o problema. veja:
D:\dev\svn_monitor>svn help relocate
relocate: Relocate the working copy to point to a different repository root URL.
usage: 1. relocate FROM-PREFIX TO-PREFIX [PATH...]
2. relocate TO-URL [PATH]
Rewrite working copy URL metadata to reflect a syntactic change only.
This is used when a repository's root URL changes (such as a scheme
or hostname change) but your working copy still reflects the same
directory within the same repository.
1. FROM-PREFIX and TO-PREFIX are initial substrings of the working
copy's current and new URLs, respectively. (You may specify the
complete old and new URLs if you wish.) Use 'svn info' to determine
the current working copy URL.
2. TO-URL is the (complete) new repository URL to use for PATH.
Examples:
svn relocate http:// svn:// project1 project2
svn relocate http://www.example.com/repo/project \
svn://svn.example.com/repo/project
Valid options:
--ignore-externals : ignore externals definitions
Global options:
--username ARG : specify a username ARG
--password ARG : specify a password ARG (caution: on many operating
systems, other users will be able to see this)
--password-from-stdin : read password from stdin
--no-auth-cache : do not cache authentication tokens
--non-interactive : do no interactive prompting (default is to prompt
only if standard input is a terminal device)
--force-interactive : do interactive prompting even if standard input
is not a terminal device
--trust-server-cert : deprecated; same as
--trust-server-cert-failures=unknown-ca
--trust-server-cert-failures ARG : with --non-interactive, accept SSL server
certificates with failures; ARG is comma-separated
list of 'unknown-ca' (Unknown Authority),
'cn-mismatch' (Hostname mismatch), 'expired'
(Expired certificate), 'not-yet-valid' (Not yet
valid certificate) and 'other' (all other not
separately classified certificate errors).
--config-dir ARG : read user configuration files from directory ARG
--config-option ARG : set user configuration option in the format:
