Brian,

Is there any explicit mergeinfo on any of these paths (you can check
with a svn propget svn:mergeinfo)?

  <url_to_repo>
  <url_to_repo>/branches
  <url_to_repo>/branches/user_branches

Since <url_to_repo>/branches/user_branches/Jeff3 has no explicit
mergeinfo, it will inherit the mergeinfo from its nearest parent with
mergeinfo. Based only on your naming scheme I'd be suprised to find
that any of these paths *do* have mergeinfo, but I won't to rule out a
bad mergeinfo value on some parent of Jeff3's as a cause of this
problem.

In steps 5-7 you have basically done this:

  Copy A to B
  Checkout B
  Merge all available changes from A to B

Which, unless you made some more changes to under A after copying it,
is a no-op; there is nothing to merge. Was this intentional? Should
step 4 and 5 be swapped maybe?

The WC-to-WC copies must have happened prior to your recreation
effort. Could you run 'svn log -vq' on some of the paths with empty
mergeinfo? Somewhere in thier history should be evidence of a
WC-to-WC copy/move, something like this (revisions, author, source
name obviously made up):

r45115 | programmerbob | 2008-05-23 23:09:08 -0400 (Fri, 23 May 2008)
Changed paths:
   A /camille/platform/src/java/com/sandcherry/tools/common/database/model/vmc/UserProperties.hbm.xml
(from /camille/platform/src/java/com/sandcherry/tools/common/database/model/vmc/UserPropertiesFile.hbm.xml:
45001)
------------------------------------------------------------------------

Then do svn diff -rr45114:r45115
/camille/platform/src/java/com/sandcherry/tools/common/database/model/vmc/UserPropertiesFile.hbm.xml,
was any empty mergeinfo added?

> The really weird part of this to me is that doing the merge anywhere lower than the root works and then I can merge at the root.

Anywhere below the root? You are able to do this merge successfully:
'svn merge <url_to_new_camille_branch>/platform
<wc_path_to_jeff3>/platform'? The reason I ask is that since the only
subtrees with explict mergeinfo under wc_path_to_jeff3 are deeper than
wc_path_to_jeff3/platform. So a merge to wc_path_to_jeff3 or
wc_path_to_jeff3/platform should attempt to merge the same set of
revisions and should almost certainly encounter the same parsing
error.
