It is not a bug, I will explain below.

What this command says is this:

For the path "/python/branches/py3k/PCbuild" as it exists at the
current HEAD revision, show me the changes that were made to it in
r59624. The command traces the history of the path. In r59625, you
can see this transaction:

   R /python/branches/py3k/PCbuild (from /python/trunk/PCbuild:59624)

The path was replaced by the path from trunk. So when running svn
log, for all revisions prior to the revision where this was replaced,
you will start to see the history entries for the path it came from.

If you want to see the history of the previous version of this path,
then you need to add a peg revision to the command.

$ svn log -v -r 59624

The book explains peg revisions better.
