Make sure that both TortoiseSVN and SVN are the same client versions. In Windows Explorer, right-click → TortoiseSVN → About. Your version information will look like this:
TortoiseSVN 1.6.5, Build 16974 - 32 Bit , 2009/08/20 08:13:46
Subversion 1.6.5,
apr 1.3.8
apr-utils 1.3.9
neon 0.28.6
OpenSSL 0.9.8k 25 Mar 2009
zlib 1.2.3
So my client version is "Subversion 1.6.5". From the command line, do:
svn --version
You will get something like this:
svn, version 1.6.4 (r38063)
compiled Aug 5 2009, 12:42:52
