Bug#643712: GNOME or GTK tabs are very slow

[Brandon Bartelds]

First, I would like to point out that I am only seeing a subset of this
issue as far as I can tell.  I have no issues in iceweasel, even when I
have 10 or more tabs open (in multiple themes), but I use a lot of gedit
and it's annoyingly slow.

I should point out that the difference between the other reports and
mine is that I was using the NVidia released drivers
(NVIDIA-Linux-x86-280.13.run) prior to the upgrade.  After the upgrade,
gdm would not launch so I tried to reinstall the NVidia drivers.
(Having done this for a number upgrades, I am familiar with the
process.)  The difference this time was that even after what appeared to
be a successful re-install off the drivers, gdm failed.

I used apt to install the Debian NVidia drivers, which in turn cleaned
out the NVidia ones and got me back up and running, but resulted in the
bug everyone is reporting (or at least the gedit part for me.)

My apt log is longer than I originally though, but I figured it might
help to share that I as well am experiencing the issue.  I've included
those packages which were updated when I experienced the issue.
