Comment 5 for bug 816762

Ew. The problem is that these two gnome-shell commits between 3.1.2 and 3.1.3:

http://git.gnome.org/browse/gnome-shell/commit/?id=6fc49b79a4e957f2442abcb23fafa33e1af64241
http://git.gnome.org/browse/gnome-shell/commit/?id=4c5f3aa97173b0b073d19a372d45487e4f1f0332

account for a gjs API change between 1.29.0 and 1.29.15 that oneiric’s gjs hasn’t yet made:

http://git.gnome.org/browse/gjs/commit/?id=0cd4538efcc0e39005c7921181c8e3687911255c

This is the same root cause as bug 811291.

Reverting those two commits will fix the problem (until gjs gets upgraded to 1.29.15, when we’ll get the same problem in reverse).
