Plugin registration error #10

Closed AttilaVM closed 6 years ago

AttilaVM commented 7 years ago

When I try to enable the add-on I get the following traceback:

Traceback (most recent call last):
  File "/home/attila/programs/blender-2.78a-linux-glibc211-x86_64/2.78/scripts/modules/addon_utils.py", line 349, in enable

    bpy.utils.register_class(AMTH_AddPresetColorManagement)
ValueError: register_class(...): already registered as a subclass

And when I open up the preferences window I get the following traceback in the terminal as Blender's stderror:

  File "/home/attila/programs/blender-2.78a-linux-glibc211-x86_64/2.78/scripts/modules/bpy_types.py", line 673, in draw_ls

    preferences = context.user_preferences.addons["amaranth"].preferences
KeyError: 'bpy_prop_collection[key]: key "amaranth" not found'

I use Gentoo Linux with vanilla Blender 2.78 downloaded from blender.org, amaranth was installed as described in the README.md.

I have the same problem on Windows 10 Blender 2.79 :

Solved by unpacking a fresh downloaded blender over my blender installation. After that I could activate the addon without any trouble.

Blender, when downloaded from builder.blender.org (or when built from the sources) will come packed with Amaranth in the 'testing' section of the add-ons. The latest version at the moment of this writing being 1.0.5, many fixes have been done since then including this one.
