I addressed that problem in this email:

http://archives.postgresql.org/pgsql-hackers/2010-08/msg01819.php

Summary: it is caused by a known weakness in cvs2svn's
branch-parent-choosing code that would be difficult to solve.

But it just occurred to me--the script contrib/git-move-refs.py is
supposed to fix problems like this.  Have you run this script against
your git repository?  (Caveat: I am not very familiar with the script,
which was contributed by a user.  Please check the results carefully and
let us know how it works for you.)
