Bug#670097: downgrading gnome-shell seems to help

[Brent S. Elmer Ph.D.]

On May 15 I upgraded gnome-shell and dependent modules.  That
corresponds to when gnome-shell started freezing.  gnome-shell was
freezing several times a day on my laptop.  It has been a day and a half
since downgrading and I have not had any freezes so far.

Here is what I had to do to downgrade after adding the snapshot
repository:

apt-get install gnome-shell=3.2.2.1-2 gnome-shell-common=3.2.2.1-2
libcogl5 libclutter-1.0-0=1.8.4-1 libcogl-pango0=1.8.2-1
gir1.2-clutter-1.0=1.8.4-1 gir1.2-mutter-3.0=3.2.2-1 libmutter0=3.2.2-1

Unfortunately, the downgrade removed evolution before I realized it.
Eventually, I got time to figure out what needed to be downgraded to get
evolution back.  Here is what I had to do to downgrade evolution:

apt-get install evolution=3.2.2-1 evolution-data-server=3.2.2-1
evolution-plugins=3.2.2-1 libclutter-gtk-1.0-0=1.0.4-1
libevolution=3.2.2-1 libmx-1.0-2=1.4.5-1 libcamel-1.2-29=3.2.2-1
evolution-data-server-common=3.2.2-1 libclutter-imcontext-0.1-0=0.1.4-2
libcluttergesture-0.0.2-0=0.0.2.1-6
