SERVER - game error -- Strength of Harvest

Xmage crashes whenever I am given the option of searching my library and selecting a card and I select Strength of Harvest.

Start with mage.players.PlayerImpl.moveCards and mage.abilities.effects.common.search.SearchLibraryPutInPlayEffect, following the stack trace from the library search triggered by Academy Rector. Reproduce the Strength of the Harvest selection scenario and inspect why the selected card reaches the battlefield-move logic with an empty or untargeted ability. Done means selecting Strength of the Harvest no longer crashes the server and the search completes.
