Issue 67009

I have a spreadsheet which has no problems when used with version 2.0.2
When using it with 2.0.3, the application crashes if I try and insert a row, or
if I try to 'save as' a different file.

This problem occurs on both the Windows and the Linux version of 2.0.3

In trying to narrow down the cause, I found that the problem was caused by a
named expression having a blank expression. eg the file contains the following:

<table:named-expressions>
<table:named-expression table:name="eric" table:base-cell-address="$Sheet1.$A$1"
table:expression=""/>
</table:named-expressions>
