Right. I’m not sure what the old version was.
I think the update UI was already broken when I noticed that its an old password and trying to update it.
I manually fixed it in the DB - as I wrote above, some fields exist multiple times and I synchronized them - after that everything works fine again. (I do have some issue with autocrypt that I think is unrelated, though).
The procedure/dialog that was buggy was: the account name was empty and thus i could not even click in some areas (like the multi account selection when starting the app or the settings dialog that should be showing the email address, I think).
