[QGIS-Developer] Crash with QgsAuthManager() in 3.x

Hi Devs,
Coding a plugin which has to retrieve json from some services with Basis
Authentication I thought to use QgsAuthManager etc... Both to hold
username/password AND the service url, so users decide by choosing the
right profile which service url/username/password to use.
Created a small ui for it QgsAuthConfigSelect(), and used something like:
auth_man = QgsAuthManager()
uri = auth_man.availableAuthMethodConfigs()[conf_id].uri()
To search for a uri of a selected config..
BUT every time QGIS crashes.
To me it looks like QgsAuthManager() should(!) be a singleton, but
isn't. And QGIS crashes in the destructing of the QgsAuthManager...
Can somebody confirm? I'll create a ticket.
Easy test?
1) Start QGIS3/master
2) open python console
3) type 'QgsAuthManager()' and ENTER
4) do this again (and sometimes again)
5) if you still do not have a crash: stop QGIS: will stop with the
following (both on Linux and Windows):
