That has to do with the widget used to represent list:string fields in forms. It simply creates one or more inputs with the same name. When there is only one item, the value in request.vars and therefore form.vars is just a string, but when there are multiple form elements with the same name, request.vars and form.vars ends up as a list. SQLFORM.accepts does ultimately convert a single string in form.vars to a single element list, but not until after the onvalidation function has been run. Feel free to submit a Github issue about this (in the web2py repo, as it is related to SQLFORM, not PyDAL).
