The bug had nothing to do with importing songs from your hard drive (zip, bin etc). The bug only kicked in when you edited the artist names or title - of those particular songs - from the tool/edit songs screen and then rebuild the database (the damage is done before the database is rebuilt it just won't be a problem until after you rebuild).
If you edited the artist names or song titles of any songs imported from the HD they are damaged and cannot be fixed with 3.2 they will have to be reimported. 3.2 will prevent this from happening in the future.
If you are getting errors but have not edited those songs then you have another problem, most likely they were zipped with Toolz set at max compression which require that you either unzip and rezip at a lower compression before importing or just unzip and import as mp3+g.
