gsettings uses the 'memory' GSettings backend / settings do not stick?!

[Daniel Hahler]

Is it expected that "gsettings" will use the memory backend?
From the extra message I do not think so, and it may be the reason why I cannot change this whitelist or the changes to the Unity starter are not being remembered through re-logins.

% gsettings get com.canonical.Unity.Panel systray-whitelist

I can confirm this bug. I upgraded my ubuntu from maverick to natty yesterday and my settings in unity won't survive a relogin. I also get this warning when starting several programs from command line.

SOLVED!!:
Hi I just read some thread in a gentoo forum and it seems as if glib needs dconf to store settings.
So I just manually installed "dconf-tools", "libdconf0" and "libdconf-dbus-1-0" and now it works.

I think this is just a missing dependancy for either glib or unity.

SOLUTION:
sudo apt-get install dconf-tools libdconf0 libdconf-dbus-1-0

log out and in again

right, it's not a bug, glib provides only a memory backend for testing and hacking, you likely want to install dconf is you need a real backend you can use, glib recommends it and applications depends on it
