window freeze when setting blank password for default keyring

[Masoud Abkenar]

The first time after my fresh install of Ubuntu 12.04 LTS, I entered Wi-Fi password to set up my wireless. Then, as usual, a window popped up for setting up the default keyring. I left it blank, like what I did for previous versions of Ubuntu. Then I got a warning message with the title "Store passwords unencrypted?" with two buttons to click: "Cancel" and "Use unsafe storage"

This window is always freezed for me. No part of this window is clickable except close (x) button on top left. Therefore I can't set a blank password for my default keyring. However, if I set a non-blank password, I don't get this message and there is no problem.

To reproduce it at a later time:

1. Go to "Password and Keys" (in terminal: seahorse)
2. Right-click on "Passwords: default" and select "Change Password"
3. Fill the "Old Pasword" text-field with something, but leave the other two fields blank.
4. Press "OK"

What happens:
* A warning message appears, but it is non-functional.

What should happen:
* A warning message should appear and by clicking "OK" it should go away.
