Comment 1 Rajeesh K V 2016-11-29 05:05:20 UTC 
There is nothing related the Touchpad KCM in the crash. Crash log has reference to Radeon driver syscall though. Is this always reproducible?

I haven't yet, noticed if this is reproducible or not -- will get back later today to confirm.

The Laptop is a Lenovo G505s with an AMD A10-5750M APU and AMD Radeon HD Dual-Graphics.
Comment 3 Rajeesh K V 2016-12-01 04:05:35 UTC 
Waiting for report on reproducing the issue.
Comment 4 Don Curtis 2016-12-01 15:36:05 UTC 
System Settings still occasionally crashes (disappears would be a better description) when setting up the Touch Pad but, DrKonqui doesn't kick in -- no Crash Dumps are available -- possibly because the System Settings window simply disappears.
