Calculation for total pages:
https://github.com/algolia/instantsearch.js/blob/v2.2.5/packages/react-instantsearch/src/components/Pagination.js#L110
totalPages = 0 because number of hits is 0 ->

in searchState there is no key = page ->

currentRefinement = 1

https://github.com/algolia/instantsearch.js/blob/v2.2.5/packages/react-instantsearch/src/components/Pagination.js#L163
disabled = false
Possible solution:
disabled: currentRefinement === lastPage || lastPage <= 1

Could be reproduced in instantsearch.js v2: https://jsfiddle.net/bobylito/cq17ut1r/

As a side note, that's a bit of an outlier as the default behavior is to hide automatically the pagination when there are no results.
