I'm not seeing where this came from.  This problem existed several months 
ago and I spent some time tracking it down, making changes and fixed it.
Problems are not showing up in the master branch.

Now my fix was backed out.  Presumably something iwasn't quite right
about it.  But now the original problem has reappeared in the develop
branch.  I presume that whoever backed out my fix is "fixing the fix"
so I can just ignore it.

I am sort of curious why my fix was backed out.  There wasn't any
issue with the serialization library until that was done.  So there
must have been some other issue.  What was it?  I'm just curious.
