[Samsung QX410] Can't suspend from the UI (Nov 6 19:21:14 snowflake gnome-session[2038]: libupower-glib-CRITICAL: up_client_get_can_suspend: assertion `UP_IS_CLIENT (client)' failed)

[Daniel Manrique]

I just installed (fresh install) Quantal on this QX410. I can't suspend from the indicator menu, or pressing power and selecting "suspend". Running pm-suspend works fine, so I know the system is able to suspend. Also, this functionality (selecting Suspend from the GUI) was fine on Precise.

Steps to reproduce:

1- Install Quantal
2- Apply all available updates
3- Press power button
4- Select "suspend".

Expected result:
- System suspends

Actual result:
- System does not suspend
- This line appears in syslog:
Nov 6 19:21:14 snowflake gnome-session[2038]: libupower-glib-CRITICAL: up_client_get_can_suspend: assertion `UP_IS_CLIENT (client)' failed

This is actually why I filed this on libupower, but please let me know if it should be assigned to another package.

Thanks!

I have identical behavior, including the same error message, on a Samsung np550p5c. EncryptFS not in use.
