Please describe the problem:
Hello,

It seems that there is a bug with gnome-mouse-properties with Gnome 2.27.4 inUbuntu Karmic.

You can follow the bug in Launchpad : https://bugs.launchpad.net/ubuntu/+source/meta-gnome2/+bug/406247

In System -> Options -> Mouse -> Touchpad -> click by tap is enabled

A workaround has found by stardust85 :
With the gconf-editor, in Desktop -> Gnome -> Peripherals -> Touchpad, tap_to_click is unchecked. If we enable this option, we can click by tab !

I think after that in System -> Options -> Mouse -> Touchpad, there are some new options in english (and my laptop is in French) about the Scrolling => O Disabled  / O Edge Scrolling / O Two-finger scrolling

Thank you !

Matthieu

PS : Sorry, it's a duplicated bug of this one http://bugzilla.gnome.org/show_bug.cgi?id=576705 but it seems that it's not followed by a dev !

Steps to reproduce:
We have to change an option with the gconf-editor to resolve the problem.

A workaround has found by stardust85 :
With the gconf-editor, in Desktop -> Gnome -> Peripherals -> Touchpad, tap_to_click is unchecked. If we enable this option, we can click by tab !

Actual results:
All is ok after that

Expected results:
I can use the click by tap now !

Does this happen every time?
After that, the GUI (gnome-mouse-properties) works great !
