Description Peter Hutterer 2012-10-08 03:35:20 UTC

Description of problem:
An XI 1.x grab on a disabled device leads to a NULL-pointer dereference crashing the server.

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.13.0-4.el6.x86_64

How reproducible:
Can be reproduced on a virtual machine (see example below), but same will happen with other devices

Steps to Reproduce:
1. xinput set-prop "ImEXPS/2 Generic Explorer Mouse" "Device Enabled" 0
2. start gimp, Edit, Preferences, Input Devices, Configure Extended Input Devices
3. change the QEMU tablet and the ImEXPS/2 mouse to mode "screen"
4. Open a canvas, click on the canvas.
  
Actual results:
On receiving the button event, the GIMP will grab all input devices with XGrabDevice(), causing a crash.
