Comment 2 for bug 614359

The gnome-shell version (2.31.2) is too old for new mutter (2.31.5)
The debian bug above is about missing libgjs0a, which was later uploaded.
It really seems that new gnome-shell (2.31.5) resolves this issue.
So please sync it with debian unstable.

There is one issue with debians gnome-shell. It depends on libgjs0a (in ubuntu libgjs0).
Debian packages gnome-shell (2.31.5), gjs (0.7.1-1) and libgjs0a (0.7.1-1) depend on libmozjs2d package, which provide the necessary mozilla javascript library (libmozjs.so.2d file).
The point is that these GS packages are not depending on xulrunner and its shared object libmozjs.so.
