That doesn't sound like a userspace bug. Have you tried different
(older/newer) kernel versions?

Cheers,

Using xserver-xorg-video-intel 2:2.19.0-5, xserver-xorg-core and xserver-common
2:1.12.3-1, I tried the following kernel versions:

(0) linux-image-3.2.0-3-amd64 3.2.21-3 (original bug report)
(1) linux-image-3.1.0-1-amd64 3.1.8-2
(2) linux-image-3.2.0-3-amd64 3.2.23-3
(3) linux-image-3.3.0-trunk-amd64 3.3.6-1~experimental.1
(4) linux-image-3.4-trunk-amd64 3.4.4-1~experimental.1
(5) linux-image-3.5-trunk-amd64 3.5.2-1~experimental.1

I also tried the newest version of xserver-xorg-video-intel 2:2.20.5-1,
xserver-xorg-core and xserver-common 2:1.12.3.902-1:

(6) linux-image-3.2.0-3-amd64 3.2.23-3
(7) linux-image-3.3.0-trunk-amd64 3.3.6-1~experimental.1
(8) linux-image-3.4-trunk-amd64 3.4.4-1~experimental.1
(9) linux-image-3.5-trunk-amd64 3.5.2-1~experimental.1
(10) linux 3.6rc3+ c182ae3

In all cases the laptop rebooted upon dragging the image displayed in the
browser. In (3), (4), (5), (7), (9) and (10) I only got reboots after trying to
drag the second time.

Also, while being dragged the rebooting image is shown as black rectangle (in
all cases), while for smaller images the image is shown next to the mouse
cursor.

Any ideas how to debug that further are welcome, since the typical recipies for
hung gpus don't work.
