Just stating:
The .xlsx contains

  <dimension ref="A1:D37"/>

in which area the actual data resides, but also

  <cols>
    <col min="1" max="1" width="29.125" style="1" customWidth="1"/>
    <col min="2" max="2" width="25.125" style="13" customWidth="1"/>
    <col min="3" max="3" width="32.75" style="5" bestFit="1" customWidth="1"/>
    <col min="4" max="4" width="31.75" style="2"/>
    <col min="5" max="16384" width="31.75" style="3"/>
  </cols>

i.e. the grey area right to the data area is covered by min="5" max="16384",
probably due to which the overflow dialog is shown. It looks like we should
explicitly ignore those column definitions in overflow detection unless cell
content data is placed there as well.

This "more columns declared than available" may or may not be related to the
crash reported here (which I can not reproduce with any version on Linux), just
to mention.
