[TSVN] Cannot replace a directory from within

We recently reorganised some old projects, to move to the /HEAD /tags type
layout. To do this we used the repository browser to move the project under
a new folder call HEAD and then relocated the copy on the client. This
appears to have worked, can files can be checked in and committed.
 
However, if I run an Update at the root directory of the project then I get
the error:
 
    Cannot replace a directory from within.
 
If I try a cleanup, it says Cleanup Has Finished.
 
Thanks,
 
Ken
