Correct. And Peter's simpler example in the debian bug page:
is a little different, but the same issue.

One other clarification is that the WC in one of the parent directories is
completely unrelated to the WC in the subdirectory.

ie. the repository (and/or method and path) for / is completely different
than the repository for /home/me/test/ and so anything it is looking for
in /home would be wrong, even in the case of the new 1.7 feature where
there is only one .svn directory for each checkout, because in my example
both / and /home/me/test would both have a .svn directory in it.

I don't know the code base well enough (or even at all), but it seems to
me that Peter's patch looked good.

I am also uneasy about the "I_LOVE_CORRUPTED_WCS" flag as a fix to this
problem, as I don't particularly love them at all, and if there were
corruption, I would want to know about it, and not silently ignore it.
