move a directory "from within"

I have checked out a subdirectory of my repos:

~/$ svn co svn+ssh://rubis/export/repos/elefant/test
Checked out revision 220.
~/$ cd test/
~/test$ svn up
At revision 220.

All is well.
Now (from another working copy) this subdirectory is moved to "new_test":

~/elefant-root$ svn mv test/ new_test/
A new_test/test
D test
~/elefant-root$ svn commit -m" testing svn... "
Adding new_test
Adding new_test/test
Deleting test

Committed revision 221.

Now from the test working copy:
~/test$ svn up
svn: Cannot replace a directory from within
~/test$ svn switch svn+ssh://rubis/export/repos/elefant/trunk/new_test
svn: Cannot replace a directory from within

Where did I go wrong ? I am hoping to be able to restructure my repos
without permanently breaking all the user's working copies.

Simon.
