Comment 1 for bug 1097649

I don't think this is a leak in compiz.

The "??" function in the valgrind trace is g_settings_class_init, which is called once when the class is first instantiated. It creates a bunch of signals (eg, g_signal_new in http://git.gnome.org/browse/glib/tree/gio/gsettings.c#n641), and as far as I can tell, never gets rid of them. In fact, searching the glib documentation, it seems like there's no way to get rid of a signal once it is created, as it is global program state.

I'd recommend changing this to "Invalid" and updating the supressions file.

(Hint: The GLib/GIO supressions file was already imported into experimental-memcheck/compiz.supp - I'd suggest using the suppressions from there).
