15.04: KWallet Migration Dialogue Wants NonExistent Password

[Buzzing Robot]

Immediately after rebooting into a clean install of the Kubuntu 15.04 22 April daily, I launched Muon Update Manager. A Kwallet dialogue popped up asking me if I wanted to migrate the existing Wallet to the 'new' Kwallet. If I proceed, I'm asked to supply a password, but I have not created a password.

 I've created no Wallets, although kwalletmanager shows "kdewallet" exists and is closed. If I try to open 'kdewallet' I am prompted for a wallet password. I have created no such password.
