Looking through these crash failure, they break down into two
categories...

dynamic column stuff in calc

There seems to be outstanding just two different distinct crashes,
which looked sufficiently non-trivial I didn't have a stab at fixing it
myself, one on reexport to ods of ooo118068-1.ods and one on import of
e.g. ooo6593-5.sxc

and

in writer, the assert of !m_bLockNotifyContentChange 
in SwTextInputField e.g. import of ooo48071-4.odt but all the rest of
the .odt failures happen in the same place
