Extractor plugin crashing after effects

Do you see any error dialogs appearing with something like "After Effects error: Cannot find image channel" or "After Effects error: file --- cannot be imported — files of type “” cannot be used as sequences." 

Those error messages are being reported shortly before the crash. 

Very interesting thanks for the info, do the crash reports mention what or why it's crashing

Yep, those crash reports get through to us. You are the only person to have hit this crash best we can tell.

No there are no special characters in the footage.

The exrs are the only sequences in the project, it doesnt matter how you bring them in, what version or computer, this happens over multiple versions on 2 entirely separate computers.  This happens in software only mode and in GPU cuda mode but only happens with multiprocessing turned on.

Surely the thousands of crash reports that get sent through register somewhere on your systems. 

I just checked in on the ticket. Looks like we haven't been able to reproduce internally and your crash is the only record of the issue. Are you using other effects before the Extractor plugin? Do the filenames have any special characters in them? If you create a new comp, bring the EXR into it and apply extractor, does it crash immediately or are there other steps we need to follow?

Any luck on find out out what this could be?

Thank you for getting that together. We'll take a look at it and see what needs fixing.

I have downloaded a freely available multi layered EXR on the web and have popped it into a project and uploaded it here (1GB)

This project crashes consistently when rendering or caching, on reopening AE 24 it says it was indeed "extractor" that has caused the crash. 

I'm not denying AE is the problem, but we don't have anything to reproduce the issue with. This isn't something we are aware or or have an existing bug written about. So however you can help us with files or materials, that'd be helpful.

I can recreate this doing the following in Ae 24 & 23:

Use any EXR sequence with multiple passes
Apply "extractor" to the layer and choose the first pass
Duplicate 2 more times, and adjust the other 2 layers to other passes within Extractor (diffuse shadow etc)
Change opacity to get the right balance
Render or cache now consistently crashes AE if multiprocessing is turned on

this works across 2 computers and 2 versions ofAe with differnent EXR sequences that are completely unrelated and createed years apart. 

AE is the problem
