System Information
Ubuntu 17.10, GTX 1080

Blender Version
Broken: b85be88655

Short description of error
This one is a bit hard to reproduce... But pretty much over the past week of using this new version of blender, the undo crashes out when we have been working on a file for around 5-30 minutes. We have tried both global undo enabled and disabled.

This usually happens when we ctrl z a few times fast... but has happened on a single ctrl z before as well as ctrl alt z and jumping back around 15 steps. It happens both in Object Mode and Edit Mode.

I know there is no reproducible steps... but it is a useability issue.

EDIT:

I have found a way of reproducing this. Please find attached the step by step process

  1. Open attached blend file -- bug.blend
  2. Add a noise texture in the node editor
  3. Connect the Factor into the colour output
  4. duplicate the noise texture and drop it onto this link
  5. Continue doing this a bunch of times, similar to below:

Selection_048.png

  1. switch to material tab (with all the material slots)
  2. mash undo really fast.

What we think is happening, is that the material preview icon cant keep up with the undo's and is causing an error. I have also attached the crash log

Think we have at least one other crash report related to undo here… But such a vague one won’t help us am afraid, please provide precise, consistent steps to reproduce the issue, otherwise we cannot investigate.
