indicator-sound crashes with uncaught error

[KVV]

After upgrade to 14.04, sound indicator used to work but then suddenly disappeared. Logout/login/reboot and cleaning pulse directories doesn't help. Sound indicator still works on the login screen though.

From .cache/upstart/indicator-sound.log:

Ping.

The last of the errors

seems to disappear after installing

   accountsservice-ubuntu-schemas

Still doesn't work, though.

I've had the exact same problem, and only realized that the "Show sound volume in the menu bar" option in System Settings > Sound was somehow unchecked after Skype was installed. I got the third error after trying to reinstall pulseaudio to fix the problem, but it was gone after accountsservice-ubuntu-schemas was installed.
