Can confirm rdata->ob_curve_cache->disp is NULL.

Tried opening that file in older builds [I have a couple of builds going back to Nov1st2018] but file is crashing those builds as well...

Tried recovering (by appending all collections into a new file), that seems to go fine [not sure everything is working correctly though...], see:
Manta asfaltica recovered.blend

I dug around a bit. There are apparently issues when using a text object as a bone shape.
Here is the same file where I converted the text object causing the crash into a mesh:
Manta asfaltica2.blend
image.png

For example, this test-file crashes Blender, when you add a modifier to the text object:
custom-shape-crash2.blend

Thanks for recovering my file.

It's weird that it was not opening on older versions.
I have been working with it and using texts as shapes for a long time and i never had this problem..
