Subversion doesn't think there is.  Rather, it knows there isn't.  Hence the
message.  The error was introduced to prevent a common mistake folks make
when they misalign their merge sources and targets:

   $ svn merge ^/trunk branches
   ^C^C^Cdangit i meant to type "branches/my-branch"^C^Caaaaagh!

Well... the --ignore-ancestry option was *supposed* to make that happen for
you.  Perhaps there's a bug?

You may need to give a more complete transcript of what you're trying,
including command-line examples and such.
