Bug Description
After updating to the latest packages in xorg-edgers, the KCM for the touchpad crashes -- or, more precisely, causes a segfault 11 in kcmshell4. I had to revert to an earlier version of the driver. Also, tap-to-click doesn't work.
Broken version:
1.6.99+
Working version:
1.6.0-0ubuntu1~
Here's the backtrace from KDE's crash handler... probably not useful, let me know if you need something more/different:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_

From a quick look at the source it looks like the problem is that the FastTap and EdgeMotion options were completely removed from the driver and synaptiks is trying to use them unconditionally.
