SVN Copy now fails with 424 FailedDependency

Hi, I'm trying to do a svn copy command to create a tag and I get the
following error :

Command: Copy C:\Projets\Logiciels9.1.XX.307 to
https://svn.aquadata.com:8443/svn/Logiciels/Tags/TestTagSVN18, Revision
WC

Adding: C:\Projets\Logiciels9.1.XX.307

Error: Commit failed (details follow):

Error: Adding directory failed: COPY on

Error: /svn/Logiciels/!svn/rvr/118520/Branches/9.1.XX.307 (424 Failed
Dependency)

This command is executed as a part of our deployment process and it
worked flawlessly in svn 1.7 before upgrading to 1.8

I was able to make the copy work by asking all the developers to release
their locks on the repository. (We have locks only on binary files) This
workaround can't be a solution because developers need to keep their
locks even when we are doing a deployment.

Here is our setup

Server : Visual SVN Server 2.6.4, with svn 1.8.1 and apache HTTP Server
2.2.25

Client : TortoiseSVN 1.8.1

Thanks
