--- Comment #2 from tinozzo123@tutanota.com --- (BTW, in the first post I erroneously wrote 5.0-17624, while I meant to write 5.0-17264. The links are correct, though)
Tested on unstable. Crashes there too. Can confirm that it doesn't crash when no controllers are connected. If you connect a controller while the app is running and then refresh the controller list on Dolphin's UI, then it will crash. Seems that the culprit is QueryInterface.
