"svn add *" and <at> sign in filename

Hi all,

I think I ran into another issue, related to @-signs in filename.
In particular
        svn add wc\B\*
results in
        svn: E200009: 'wc/B_at_2.txt': a peg revision is not allowed here
if there's a file "@2.txt" inside "B".

Here's a script to reproduce this: https://skydrive.live.com/redir?resid=8FD4EC3161ABA67A!941
(the same file is also attached to the message)

Can anyone confirm the issue?

Best regards,
Igor Varfolomeev
