Hello Khairul, or anyone else affected,

Accepted gnome-desktop3 into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

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.
