Can't access KDE Wallet after the latest updates

[Sherif]

After the latest updates, I'm asked to enter the KDE Wallet password instead of accessing the wallet directly. I think the password I enter is correct, but I don't the error in Snapshot1.png.

Fix it quickly. I can't access all of my browser passwords in the wallet.

After a fresh installation of Kubuntu 15.04, I found this bug exists, after updating all Kubuntu pakcages.

This bug is very critical, because it cause you to lose access to data.

This bug is either fixed by updates or the workaround in comment 5 I applied from bug #1435061. Sorry, I don't know what fixed it.
All application could access the wallet and I only entered the password only once. It was to connect to Wifi.

No, it wasn't fixed. After logging out then logging in, I was asked to enter password for e-mail. After entering it I got the error. I also got the error, after entering password for Chrome. I didn't got the error the first time for Wifi.
The wallet seems to open for all if you enter password for Wifi only.

Status changed to 'Confirmed' because the bug affects multiple users.
