The ubuntu driver showed up as 0.14.3 and upstream 0.14.4 had a bunch of fixes for 64 bit issues.
I was having the same problem with random pastes caused by phantom 3rd button presses each time I put my finger on the touchpad (even if I had "disabled" tapping). I have since manually updated to the latest version from the git tree. It's working a lot better now.
I would recommend the synaptics driver is updated to the latest release.
