The first cause is the most likely, if you are getting acetic acid from oxidation it is likely you will have some more severe off flavors.  The flavor is most often formed by particular yeast strains, primarily lager, and is pronounced by poor fermentation conditions such as high temperatures, insufficient pitching rate or other factors that could strain the yeast.  Long lagering is supposed to mellow the flavor.
