System Information
Win7, Nvidia GTX 1080ti

Blender Version
Broken: blender-2.80.0-git.9abcf56fa88-windows64
Worked: 2.79

Short description of error
When moving bones to another layer while in pose mode blender crashes

Exact steps for others to reproduce the error
Use my blend file. I tried reproducing the error with a simpler scene but it didn't cause a crash.

  • Open scene
  • Switch to pose mode
  • Select one of the longer tail bones and move it to the second layer
  • Go to the Layers in the Skeleton menu of the Armature and click the first one

At this point Blender should crash.

As this rig is part of a production and provided only for debugging it would be nice if someone could remove the link after the issue has been resolved.

Confirmed, bPoseChannel is NULL (cannot be found in BKE_pose_channel_active() when its on a disabled layer)

I guess for widget drawing it should be OK to just do nothing if we're not getting active pose channel back, fix incoming...
