This sounds like a known form of breakage at Google. It's related to 
their message de-duplication tricks and to the way they assemble "All 
Mail." I have not tested it, but it might work to first move a message 
to a non-GMail account, empty the trash and sync the GMail account, then 
move it to the other GMail account. That way, GMail will not 
continuously have a copy of that exact message to treat as the "real" 
one to which all other references point.
