Message:
Hi,
The error pop up is repeatable and the layer features start disappearing.
The file is not damaged, but when reopening the layer, a new object with no
geometry (empty geometry collection) appears in the attribute table.
I was editing a Natural Earth shapefile. The tools I used were the ''split
line'' and the ''move vertex''. I encountered the error about 5 times, and
each time I was doing some vertex adjustments.

Message:
Seems related to a feature with no geometry (null geometry).
Is the error repeatable ? Which tools were you using just before the NPE ?
Can you give the sequence of operation to produce the error ?
