To reprocuce:

1. Open ply list in my uploaded zip file
2. Filters-\> Group Time Step
3. Press ‘D’(for select points on) to select point
4. Click somewhere in the view which shows filter output

I have tried to upload file, but some error occurred, I put the zip file [here](https://drive.google.com/file/d/1BSaBbQu4vsuUEnEhhOjFVLP124jHFk0w/view?usp=sharing) in google driver.

Some additional information I have tested:

1. Select points through(‘G’) will not crash as ‘D’
2. Group Time Step will print Warning message:  
Warning: In D:\dev\ParaView57\ParaViewCore\ServerManager\Rendering\vtkSMPVRepresentationProxy.cxx, line 277  
vtkSMPVRepresentationProxy (0000014BC185C090): Could not determine array range.

Hi,

I couldn’t reproduce this in ParaView 5.9.0-RC3. There was a recent fix to a crash when selecting points in large datasets. I recommend upgrading ParaView if you can.

I have tested 5.9RC3, fixed:) Thanks for your reply!

Could you please tell me which merge requests or issues fix this bug? I may try to pick these changes to my local repo. In fact I am using v5.7 and waitting to upgrade paraview for non-ascii filename reading issue fixed ([here](https://discourse.paraview.org/t/how-can-i-read-non-ascii-filenames-from-pvpython/3121/15)).
