I have a "normal" google mail account which I am using with icedove (using oauth2, current version from testing). A couple of days ago, icedove stopped being able to fetch or send mail (with some version of "can't connect to server" or so). I then deleted the oauth2 credentials, which I suspected as likely culprit.
Now, when I try to connect, icedove opens an empty popup window with the title "Enter credentials for [my email address] on imap.googlemail.com. However, this window is blank except for a visible (but not selectable) address bar. Usually, this window should serve a website that handles the oauth2 login, I assume. This sadly leaves me unable to connect to my gmail account for the time being (a workaround would be to use password login, I guess).
