Comment 1 for bug 1579837

From unity8.log:

Could not set password mode: "Did not receive a reply. Possible causes include:
the remote application did not send a reply, the message bus security policy blo
cked the reply, the reply timeout expired, or the network connection was broken."
qml: Error setting security method: Could not set security mode

I believe we make that "setPasswordMode" call synchronously for technical reasons, which explains the freeze. So the wizard tried to synchronously set the passcode to what the user asked and it times out. Which explains the freeze and why it isn't kept on a reboot.

Not sure why it times out yet.
