I'm suprised no one has mentioned this but the problem could simply be that the chainring is not perfectly round. On my old cranks i always had the same problem, then since i have been using sugino 75 cranks and a zen chainring the problem has gone.
Its no big deal though so ride your bike and enjoy it.
