For future searchers' benefit, the error code should have been E155000.

It's a client-side error.  I think it means working-copy recorded data
doesn't match data newly received over the wire, but I haven't had time
to confirm this.

The relevant client-side library was rewritten between 1.6 and 1.7,
which would explain why 1.6 and 1.11 behave differently.

Note that 1.11.x is no longer supported; only 1.9.x/1.10.x/1.12.x are
currently supported.

In 1.12.x (and probably 1.11.x too) the error should only be raised if
DEST existed and was a working copy before the 'svn co', so try specifying
a new or empty directory as DEST instead.
