If when trying to connect with WebVNC you get a message on the Amahi box "Enter password for default keyring to unlock" then you need to delete or rename the default keyring:
To delete:
rm ~/.gnome2/keyrings/default.keyring
or backup:
mv ~/.gnome2/keyrings/default.keyring ~/.gnome2/keyrings/default.keyring.bak
