Comment 1 for bug 731043

Seems that your Keyring is closed.

Read this chapter from the Popper Help:
There must be a password for each user account. Characters are shown as

dots. Passwords are managed by Gnome-Keyring. When you key it in for the

first time or modify an existing password, all changes will be stored to

Keyring. Popper retrieves your passwords when checking for new emails.

Therefore the Keyring has to be unlocked at every start of a user-session

unless the password has been set to BLANK. If want to know more about

keyring you should take a look at the programm "Seahorse" or its

documentation. Seahorse can be found in Ubuntu menu:

system->preferences->passwords and encryption.
