Jenkins Subversion Tagging Plugin, version 1.16 fails to tag on a newly created branch.

Subversion tag checks out:

Subversion copy failed. svn: E160013: Path 'https://subversion03/svn/uniregrepos/branches/rel_20130413/src' does not exist in revision 1,060
Build step 'Perform Subversion tagging on successful build' marked build as failure

It fails because the SVN Global Number for the newly created branch starts at #1061. The 'subversion tag' plugin picks SVN Global Number #1060.

When I tried to commit to the newly created branch, the SVN Global Number is incremented and the subversion tag plugin works.
