Bug#665808: It appears that I am also affected -

[Billy Block]

It appears that I am also affected -

Gnome-shell seg faulting at login -
looks like it tries to start (twice) then crashes.
  - the top panel flashes on twice before the "oh no" screen.
Started after an upgrade yesterday (03/25) - all was fine until i rebooted
  - the upgrade was pretty benign - some nvidia stuff, some xserver 
stuff, the only bug apt-list bugs listed was a python2.7 conflict 
(looked pretty minor).
Same "oh no" screen with all users
I disabled all gnome-shell extensions - the problem persists.
Appears to work fine in classic mode or openbox.

from dmesg: gnome-shell[4301]: segfault at 1 ip 00007f047ca344c7 sp
