Dekko 2: Unable to add multiple accounts

[nontrivial]

When I try to add a second IMAP mail account in Dekko 2, after entering my email address and password I get a modal screen saying "Searching For Configuration" that never goes away. It seems folks have had this problem before and solved by a factory reset, but I just did a factory reset trying to get GMail contacts syncing. (Which didn't work, BTW, I had to import them from a vCard file). I've tried putting in various random information for the email address and password, hoping to get it to error out to a screen where I can enter the information manually but it never gets there.

So does anybody have any suggestions on how to get bast this bug? I am running OTA-22 on a nexus 5.

So if you choose Google instead of IMAP it bypasses whatever issue it has, and you can enter the information manually.
