[Bug 1002736] Re: [xorg-edgers] Synaptics driver crashes KDE touchpad control module

This time, when I run

kcmshell4 kcm_synaptics

I first receive this GUI dialog error (click for image):
https://lh5.googleusercontent.com/-idnLMSGEdLA/T7vF5QfcK0I/AAAAAAAAK5w/6gr0plxWt7M/s607/kcm-synaptiks-error.png

OKing or Canceling out of that raises the GUI KDE crash handler with
another segfault 11 in kcmshell4.

The crash handler's backtrace shows this:

Application: KDE Control Module (kcmshell4), signal: Segmentation fault

Perhaps more helpfully, there is much more backtrace info in the console window this time:

Does this hint that perhaps even more options -- at least the circular pad one -- have been removed? I wonder why the functionality of Synaptics driver appears to be undergoing some reduction?
