SVN::Client->log problem

This may be just a stupid user trick, but I'll ask anyways. I can't seem
to be able to get the log entry for a revision of a file that's been
copied to a tag/branch, but I cant get the entry for the main file in
trunk just fine.

Here's and example. Let's say I have just one file in trunk, and have
copied trunk into tags:

http://example.com/svn/project/trunk/foo.txt
http://example.com/svn/project/tags/0.01/foo.txt

Both files are at revision 22.

Now, here's the simple perl:

> use strict;
> use warnings;
> use SVN::Core;
> use SVN::Client;
>
> my $client = SVN::Client->new(auth => [SVN::Client::get_simple_provider()]);
>
> $client->log(
> ['http://example.com/svn/project/trunk/foo.txt'],
> 22,
> 22,
> 0,
> 0,
> \&_process_log
> );
>
>
> sub _process_log {
> my @logs = @_;
> warn join ', ', @logs;
> };

As is, I get the last log entry just fine.
Now, if I change http://example.com/svn/project/trunk/foo.txt to be
http://example.com/svn/project/tags/0.01/foo.txt

I get this instead:

> HTTP Path Not Found: REPORT request failed on '/svn/!svn/bc/22/project/tags/0.01/foo.txt': '/svn/!svn/bc/22/project/tags/0.01/foo.txt' path not found

Both urls from the top work in a browser, so the files are there as far
as WEBDEV is concerned, and svn log -r22 works on both urls as well.

Changing the $discover_changed_paths and/or $strict_node_history options
has no effect.

What am I missing here?

This is under 1.2.0 on the client/server.

Thanks,
