V599 crash with editing the text fields list in Footprint Properties

Version info at the end of this file.

This Post was UPDATED 5/12/2020 to fix some detail errors

This file was downloaded from SnapEDA. It had a number of added text entries I wanted to delete. ADUM5242ARZ.lib

To reproduce:

With this file in you library:

• Open it in the Symbol Footprint editor.
• Delete (from the bottom, although it may not matter) the 8 text lines one at a time. I used the trash can icon to delete.
• OK - window will close
• Reopen the same footprint, presumable all the deleted text will be deleted, but it is not.
• Delete the remaining text lines.
• OK --> all open Kicad window disappear. Repeated it a few times.
