Specifies the type of function which is called just after an
extended error instance is created and its fields filled. It should
only initialize the fields in the private data, which can be
received with the generated *_get_private() function.
Normally, it is better to use G_DEFINE_EXTENDED_ERROR(), as it
already takes care of getting the private data from @error.
