Update to 5.1.1: Integrity constraint violation on create unique index

[russclewett-mw]

CMS version: 5.9.9

When upgrading from 5.0.3 to 5.1.1 the migration fails and I get the following error

create unique index idx_mifngscdhwctusonlnxihrrbvtovzxngfwij on {{%googlemaps_addresses}} (elementId,siteId,fieldId) ...Exception: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '5774-1-61' for key 'googlemaps_addresses.idx_mifngscdhwctusonlnxihrrbvtovzxngfwij'

+1 I'm also experiencing this.

So far i'm noticing it's snagging on revisions with a google map field. Something in that update migration is duplicating the address for a revision, then complaining about the duplicate saying there's already an address with that element id.
