stept to reproduce:

1. install drupal.
2. in drupal make a second user named foobar
3. install a vbulletin board.
4. make a regular vbulletin user name foobar
5. install drupalvb module
6. try to change the role for foobar in drupal
7. it tells you there is already a user with that name and email, even though you were trying to edit an existing user

there's a couple workarounds, but I think this is a fundamental clash that should be avoided:
- disable drupalvb, edit role, enable drupalvb
- disable drupalvb, delete drupal user, enable drupalvb
- manually edit the role in the db tables

Hmm, sorry about that, I did search for it but have no excuse as to why that one got passed me.
