This bug was fixed in the package gnome-desktop3 - 3.2.0-0ubuntu4.1
---------------
gnome-desktop3 (3.2.0-0ubuntu4.1) oneiric-proposed; urgency=low
* debian/patches/02_refuse_to_break_GL_compositors.patch:
- Add extra paranoid checks to fail gracefully in the case of errors in
check_gl_texture_size. Eliminates (otherwise harmless) crashes.
(LP: #862161, LP: #862998, LP: #861804, LP: #861548)
- Wait for check_gl_texture_size no longer than 500msec. Ensures that
this check will not block the desktop, as in (LP: #871188).
* Remove debian-changes patch which accidentally reverted the change meant
to be applied in 3.2.0-0ubuntu4.
