Bug Description
I am a Sputnik beta participant, and have the high-end XPS 13.
With tap-to-click disabled, occasionally a tap (not hard enough to depress the clickpad) still gets turned into a click.
Note that this does not happen constantly, but to reproduce, run this:
$ xev | grep Button
Place your mouse cursor over the xev window, and begin tapping the trackpad (again, not hard enough to cause a hardware click). The only place I can get it to occur is on the bottom edge or the bottom corners of the trackpad. Unfortunately this happens to be where my thumb sits most of the time, which means this issue bites me.

I have attached a patch that fixes this problem by making sure that the "tap" bit in the header is handled even if the trackpad reports the number of fingers in contact to be zero.
