apps->admin->database export->data export->generate
the file never becomes available, message in console says
CommandError: Unable to serialize database: maximum recursion depth exceeded in comparison

here's my notes

Using tendenci 15.1
below: a long traceback in a recursive plunge from attempting a database export. I'm pretty sure it has something to do with
the last line of tendenci/apps/events/models.py Event init

def init(self, *args, **kwargs):
super(Event, self).init(*args, **kwargs)
self.private_slug = self.private_slug or Event.make_slug() <<<< or maybe this one
self._original_repeat_of = self.repeat_of <<<<<<<< I'm guessing this is the trigger

eventually it crashes doing something with events.Organizer:
CommandError: Unable to serialize database: maximum recursion depth exceeded in comparison

the 19-line recursive loop is marked with ----

I found a breakpoint 8000 here to be useful, after hitting events.py#2409 init : db, init_list, row[model_fields_start:model_fields_end]

It does this from both a manage.py command and the internally generated dump at http://thinkc.local:8000/explorer/export_database/
