System Information
Operating system: Windows 8.1
Graphics card: NVIDIA 740M

Blender Version
Broken: blender-2.80.0-git.84c06e996a7a-windows64
(example: 2.79b release)
(example: 2.80, edbf15d3c0, blender2.8, 2018-11-28, as found on the splash screen)
Worked: (optional) ?

Short description of error
bad check/uncheck code for some add-ons result in this error:
bpy.utils.register_class(class_["class"])
ValueError: register_class(...): already registered as a subclass
Exact steps for others to reproduce the error
try to check and uncheck some add-ons.
This are the add-ons I find with errors:

  • Oscurart Tools
  • Scatter Objects
  • UV Magic

Based on the default startup or an attached .blend file (as simple as possible).

Please create another report for the UV Magic addon. This should be handled by @Nutti.

This bug should solve the task is about the error:

  • how to take the error by the Blender 3D software when add bad add-on and respond into correct way and depends by development team.
ValueError: register_class(...): already registered as a subclass

Basic rule: Any software cannot have output an error for a designed task.

I committed the newest codes of Magic UV.

https://developer.blender.org/rBA48c4cad2c4211c52f71f5ab39b94538608ecd90e

From my environment, it works fine.
If you still have problem, please create new report.
