I just got the same messages by metacity 1:2.34.1-1ubuntu11, and key bindings like <Alt>Tab for switch_group stopped working. Downgrading to 2.30.3-0ubuntu8 did not help, and a newer version is not available for Ubuntu 12.04 as of 2012-08-09. I ended up removing ~/.gconf/apps/metacity/ and restarting metacity. This somehow made the issue disappear but of course my settings were lost and I restored them manually with gconf-editor.
