Do not call cmsCloseProfile() on handle in the caller, this will be done when the self object is finalized. Treat the profile like it’s been adopted by this module.

To handle the internal error callback, you should use the thread-safe creation function, e.g. cmsCreateNULLProfileTHR(). The context_id should be set as the value of Colord.Icc.get_context() for this object.

Additionally, this function cannot be called more than once, and also can’t be called if Colord.Icc.load_file() has previously been used on the self object.
