Subversion - Cleanup Failed To Process The Following Paths

SOLUTION I
1) Try and determine what rev your Working Copy is checked out at -
file->properties->subversion should tell you this, but the picture may
be less clear if you have mixed revisions.

2) Check out a new Working Copy at the revision you've just determined

3) Create a patch from your broken Working Copy

4) Apply the patch to your new Working Copy

5) Continue using the new one. Delete the broken copy when you're
confident you no longer need it.
