** Description changed:
- On Precise, when I plug in the USB dongle that comes with a Logitech
- H800 headset, xorg segfaults.
+ SRU Justification
+ =================
+ [Impact]
+ On i386 machines, plugging a headset with buttons in will crash an existing X
session or prevent an X session from starting.
+
+ [Development Fix]
+ The crash is due to an ABI mismatch between xserver-xorg-input-evdev and
xorg-server. A rebuild of the evdev input module fixes the issue.
+
+ [Stable Fix]
+ Same as development fix.
+
+ [Test Case]
+ Plug in a headset and see if X crashes.
+
+ [Regression Potential]
+ Practically zero.
+
+ Original bug report
+ ===================
+ On Precise, when I plug in the USB dongle that comes with a Logitech H800
headset, xorg segfaults.
