Short description of error
Latest builds crash if I want to disable some add ons.

Across crash on "Load factory setting" (I posted here I found few addons that crash immediately if I want to (disablet them.

First aid to get "Load factory setting" works I had to moved userpref.blend and startup.blend files out of config folder.
It helped. Than I created new ones, and enabled "my" few most needed addons.

Few of them always crash when I want them disable.
(If they are ON, blender crash on "Load Factory Setting".

  • Animation Nodes
  • Asset Manager
  • Node Wrangler

(Doesn't matter if any other addon is enabled.)

  • Blender Cloud - is special one, this crash if "Copy Attributes Menu" or "Import Images as Planes" addons are ON. If they are OFF addon works.

(Yesterday I would swear that with build from 10.10.2016 I could disable "Blender Cloud" addon after "Cycles Render" addon. Today zero relation in behavior.)

Command Line
And just don't be this enough easy, I tried to do the same with running blender from terminal.
And ... it behaves differently.

  • Asset Manager - crashed when I took it ON (not OFF as usually) several times, but now I can't replicate it
  • Blender Cloud - can be disabled without crash, terminal message:
search for unknown operator 'PILLAR_OT_browser', 'PILLAR_OT_browser'
search for unknown operator 'PILLAR_OT_browser', 'PILLAR_OT_browser'


  • Copy Attributes Menu - crashed now too and after that Blender Cloud start to crash too with
search for unknown operator 'PILLAR_OT_browser', 'PILLAR_OT_browser'
search for unknown operator 'PILLAR_OT_browser', 'PILLAR_OT_browser'
blender(5216,0x7fff7895d000) malloc: *** error for object 0x7fc9adc870d0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6
  • Now I'm out of focus, now these two crash blender in strange order ...

I spend few hours trying different combinations to see what interact with what.
I m discharged, patience over,sorry.
One more thing that was noticeable, in some cases it helped wait a few second before disabling another one.

cannot reproduce crash, but console get's flooded with unknown operator reports, i wonder if the classes are getting reg/unreg properly?
possibly could try class list for reg, as addons using this method seem unaffected.

Just in case it can help somehow ... what about this cookbook?

  • dis Wrangler first = OK
  • dis AnimNode / dis Wrangler = error message
  • dis SetOrigin2Selected / dis AnimNode / dis Wrangler = CRASH
  • dis SetOrigin2Selected / dis Wrangler = OK

(dis SetOrigin2Selected = always error message)

seems like the crashes here are caused by animation nodes addon, closing as resolved.
