While everyone is anticipating a new release shortly the following
appeared on the TortoiseSVN dev list and hasn't yet made it over here yet.
I thought it better to pass on earlier rather than later and sincerely
hope it's not going to upset the originators

You mean trunk

I can reproduce this in r5039. Interestingly, running update on the
original trunk does not generate the duplicate, only a fresh checkout.
That's bad :-( You should report this on the subversion dev list. It
may be a known bug, but I find the SVN issue tracker very hard to search
(I either get no results at all, or hundreds). Having said that, if they
do know I would have expected it to be serious enough to fix between
1.2 and 1.3 so maybe it is a new bug.

Hard to know what it should report. Evidently Subversion is broken here,
but I suppose we should report the same as the CLI.
