I haven't kept notes beyond what are in the bug reports, I guess things
have improved a little over time.   I've tried at least 11.10, 12.04,
12.10, 13.04, and 13.10 on this unit.  Before that I had another, older
model and it had similar problems but worse.  But both typing and using
the track pad trigger false clicks.  It does not happen on the same
hardware using OS X.  I recall for sure that the false click problem was
not apparent in 2009.

Title:
  Laptop keyboard activity and touchpad movements often interpreted as
  clicks

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On a MacBookPro8,2, the track pad often fires off a click even when it
  is not pressed.  This can happen when typing on the keyboard (not
  touching the trackpad) or when actually using the mouse but not
  clicking.  Such events make it fairly unsafe to use GUI applications
  that do not have an "undo" function for each possible action.  Nothing
  seems to make the false clicks more or less likely to happen.

  WORKAROUND: Use external keyboard and mouse.
