Can't redo this error. f81aeac2bc98624d1fd7de9a615303637cea39c1

I'm also unable to reproduce the error, however, I'm on windows. Blender 2.8 26d5a3625ed.
Could this be your issue? https://developer.blender.org/T57596

I'd recommend re-downloading Blender if the issue persists.

I recorded the crash: (is not a vital thing to me, i was just testing the new version, and this happened).

Also can't reproduce.

Sebastian Parborg (zeddb) triaged this task as Needs Information from User priority.

Is this still an issue?

I can reproduce this issue on Linux x86_64.

The trick to getting it to crash is clicking the plus without dragging.

Steps to reproduce:

  1. New General Project
  2. Modeling View
  3. Select Cube
  4. Change to Spin tool
  5. Click one of the plus buttons (without dragging).

Version: blender-2.80-141c6073ca39-linux-glibc224-x86_64
System: i7-3820 / GeForce GTX 670 / NVIDIA X 390.77
Linux: 4.15.0-43-generic / Ubuntu Xfce 18.04.1 LTS

I format my pc with the latest Ubuntu, is working fine now, maybe something related with Ubuntu Mate?, don't think so do.

@David Bennett (complistic) I still can't reproduce this on my end. However, those are not the latest nvidia drivers (410.93 is):
https://www.nvidia.com/Download/driverResults.aspx/141700/en-us

Check if you can't get those installed via the package manager in ubuntu and see if the problem still persists (make sure to keep up to date with blender betas too!)

@Sebastian Parborg (zeddb)

390.77 are the latest available in the regular "Additional Drivers" section of Ubuntu 18.04.1 LTS so I thought I would try the blender update first in case updating the drivers fixes it. (so I can get you more information)

Updating blender to blender-2.80-445433a6913f-linux-glibc224-x86_64 results in the same problem, here is a video of the problem:

One thing I do notice is that if I don't deselect and reselect the cube it sometimes works.

Also here is the output from /tmp/blender.crash.txt :

I'll look into updating my Nvidia drivers when I get a chance, probably tomorrow.

Thanks,

This is likely a bug in the tool logic looking at the backtrace, not the drivers,

I couldn't crash this tool from basic testing, please give exact instructions for how to redo + test file if needed.

@Campbell Barton (campbellbarton) The steps to reproduce I've found that cause this crash 100% of the time for me are:

  1. New General Project
  2. Change to Modeling View
  3. Deselect Cube
  4. Select Cube by dragging the selection area
  5. Change to Spin tool
  6. Click one of the plus buttons (WITHOUT DRAGING).

Campbell Barton (campbellbarton) raised the priority of this task from Needs Information from User to Confirmed, High.

Thanks, Step 3 & 4 are important since you're spinning half the cube's faces.

Always give exact steps in future to avoid confusion.

@Campbell Barton (campbellbarton) Just tried this in blender-2.80-08ab09cf04d9-linux-glibc224-x86_64 and it works, thanks!

@David Brum (davidbrum) I trust this is working for you also?
