Bug Description

After an upgrade to xserver-xorg-input-evdev | 1:2.6.0-1ubuntu1, X crashes at start when it adds the input device.
Downgrading to xserver-xorg-input-evdev 2.3.2-6ubuntu3 fixes the problem.

Here is the relevant bits of the Xorg.log:

I very much doubt this is a bug in xorg-server (xserver 1.9 series).

The crash ([ 11.710] segmentation fault at address 0x1010) happens very clearly with Nvidia graphics cards and with nvidia-current binary drivers.
In fact with nvidia, the system will not even boot to gdm.
Also using wireless or bluetooth mouse causes x to crash.

But it is important to notice that this happens only with xserver-xorg-input-evdev_2.6.0 input driver (controlling mouse and kb).
Downgrading to previous version (2.3.2) fixes this completely.

This has also been tested with vanilla xserver-xorg-input-evdev (2.6.0) in Arch Linux and xserver 1.9.3 with same results.
So this is not Ubuntu-specific issue.

This might not even be a bug at all.
Evdev 2.6.0 might simply not support xserver 1.9.
Note, that evdev works well with xserver 1.10 series.
This can also be tested with the packages in xorg-edgers PPA.

The only issue, which can be considered a bug, is that this evdev driver (2.6.0) in Natty official repos:
- depends erraneously on virtual package xorg-input-abi-11 (which refers to xserver 1.9 series as a matter of fact)
- provides erraneously a virtual package xserver-xorg-input-11 (also refering to xserver 1.9 series).

Correct dependency is xorg-input-abi-12 and correct provided package is xserver-xorg-input-12.
This way this evdev 2.6.0 could not be even installed on systems with xserver 1.9.

for the downgrading part: it really helps.

Here is how i did it:

wgetted the package from https://launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/1:2.3.2-6ubuntu3b1/+buildjob/2109048

and sudo dpkg -i xserver-xorg-input-evdev_2.3.2-6ubuntu3b1_amd64.deb

I wrangled an unstripped version of evdev into my system and I managed a better backtrace (I'm coming from bug #709915):

Jean-Baptiste: you've noted in the summary that X is crashing in RemoveDevice() -- do we have the same bug here?
