Example file from Word

Attached user made file contains a column chart.
Opening this file in Writer causes the processor and memory use to skyrocket
until memory is exhausted.

Steps to reproduce:
1.      Open attached file

Actual results:
Writer stops answering, uses huge amount of memory and after a few minutes
opens the document without the chart data, with only an empty chart.

Expected results:
File opens correctly.
