Message:
Ok. Here's another instance.
1. Create 2 layers.
2. In one of the layers, draw several polygons or lines. Merge some of
these objects.
3. Reorder the layers

Thanks Andrei, this helped much.
There is a bug in MergeSelectedFeatures which should be fixed in r3518
Let me know if you noticed also this NPE without using
MergeSelectedFeatures
before I close the bug.

Message:
I think I discovered why this error appears.
It is somehow related to the attribute schema and the ''merge selected
features'' command. If you follow these steps you will get a Null Pointer
Exception:
1. Draw some lines or polygons in a new layer
2. Merge some of these objects (you can also create multilines or
multipolygons).
3. Insert a new field in the layer attribute schema. Apply the changes.

Message:
The initial datasets are valid. The 2 shapefiles can be downloaded from
here:
https://www.wetransfer.com/downloads/8e74a21a7675bf2dc9e2af3a7b1a39c320130420191545/bd203cef23182ff13d32115f7846ef1520130420191545/5f318a
I don't remember the sequence of operations because I received this error
several times in different contexts. I was snapping, splitting, and merging
line features and the error just came out one time when deleted a vertex,
another time when merging 2 lines, when snapping 2 vertices. I don't
remember the feature id's either. I will try to redo the steps, but it
looks the error just comes out randomly.

Message:
Can you check if your initial dataset is valid with the validation tool.
Would be very helpful if you could provide
- a shapefile
- a sequence of operation and a feature id which allow us to reproduce
exactly the bug you noticed
Thanks for your help

Message:
I now notice that the file is actually damaged afterwards. The feature with
empty geometry is in fact a random line feature from the dataset with the
geometry removed.

I also received this error while merging 2 line features.

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 ?
