Short description of error
bad check/uncheck code for some add-ons result in this error:
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:

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