For those which are not familar with german: Unbekannter Fehler in der Erweiterung is something like Unknown error in the extension .
I am 90% certain this is related to the gnome-shell-3.2.1-r2 upgrade. Will look into it.
The problem was that to improve shell stability, gnome-shell-3.2.2-r2 added a patch from 3.3.x that prevented disabled shell extensions from being auto-loaded anyway on shell startup. This patch involved adding some more values to the EXTENSION_STATE enum - and apparently gnome-tweak-tool-3.2.2 could not deal with those new values. Fixed in gnome-tweak-tool-3.2.2-r2, thanks for reporting! >*gnome-tweak-tool-3.2.2-r2 (10 Jan 2012) > > 10 Jan 2012; Alexandre Rostovtsev <tetromino@gentoo.org> > -gnome-tweak-tool-3.2.1.ebuild, +gnome-tweak-tool-3.2.2-r2.ebuild, > +files/gnome-tweak-tool-3.2.2-gnome-shell-3.2.1-r2.patch, > +files/gnome-tweak-tool-3.2.2-missing-schemas-error.patch: > Fix gnome-shell-3.2.1-r2 compatibility (bug #398385, thanks to Juergen Rose > for reporting) and report a more useful error on missing schemas.
