Crash on proxied rig with custom bone shape and driver targeting the rig
Closed, ResolvedPublicBUG


System Information
Operating system: Windows-7-6.1.7601-SP1 64 Bits
Graphics card: GeForce GTX 760/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 445.87

Blender Version
Broken: version: 2.83.0, branch: master, commit date: 2020-06-03 14:38, hash: rB211b6c29f771
Worked: (newest version of Blender that worked as expected)

Short description of error
I found out that it is happening either because of the text shape of the top bone (letter A) - without it its not crushing
and if the "shapes" collection is inside the "teller" collection its not crushing

Exact steps for others to reproduce the error

*open new blender file
*link the "teller" collection (from the file attached)
*make proxy "bank teller_Armature"
*save file and close blender
*open it again - crush

Thanks :)

Philipp Oeser (lichtwerk) changed the subtype of this task from "Report" to "Bug".

Can confirm.

This is due to the Custom Bone shape on Bone P (which is a text object -- in this case A_shape).
Removing the A_shape as a custom bone shape from P and saving Rigging_Teller_Bug.blend makes the issues go away.

We had related T61035: Draw manager crash opening file with curves and T73252: Crash with links and Make proxy, both closed without proper solution.

@Sybren A. Stüvel (sybren): can you reproduce this time? is this file simple enough?

here is the backtrace (again -- it is similar to the one in the other reports)

Philipp Oeser (lichtwerk) renamed this task from Crush on importing linked character with proxy rig to Crash on linked character with proxy rig and a bone with a text object as custom bone shape.Jun 10 2020, 1:17 PM

I can confirm the crash, but it would really help if the file was trimmed down. If it's just one bone with a custom shape that causes this crash, then there is no need for the entire rig + the model.

Hi, Here is a simpler scene just with one bone and shape.
In link with proxy still crush
