Not really, but the way I would debug this is to see how
XmlFilterBase::openFragmentStream() at
oox/source/core/xmlfilterbase.cxx:495 gets called in the good case, and
then hopefully the backtrace would give you some idea how it's not
called in the bad case.

My first guess would be some static variable, but who knows.
