Can you redo from scratch and provide another file where this happens?

Cannot reproduce from scratch here, could you provide your .blend file?

No, this is not a bug.

After testing the file, there is a special situation in the right lower part of the drawing. As the end of the stroke is projected to fill small gaps, in this situation is not closing the stroke totally. This is a limitation of the fill in a 3D space.

To fill, just move the point selected near of the horizontal line.

Ok, it is a known limitation - but why there is a Limit Scale Constraint when you can't limit the scale properly? It causes me a lot of trouble on a complex rig I am working on.

I recognised something else.

I am using the default settings with AV-sync (see attachement)
It is hardly to reproduce the case – it sometime happens

I see.
I think the first thought is - i am in a kind of visual painting mode environment and i am dealing with some colors from blue to red - i am using a brush tool and expect the behaviour of usual painting processes.

The weight painting falloff should be similar in both directions. A weight value of 0 should falloff towards red and a weight value of 1 should falloff towards blue.

New found crash routine:

I tested a few values and it seem that it only crashes on the Emission:Number Value of 0 - also in advanced mode

I just updated Blender.
I have the same problems.
Changing Properties or switching to Particle Edit are crashing Blender.
