This is with autoturn on:

A banished ogre and Lady Irane stand faceing each other, 1 empty tile between them.

Lady Irane moves toward ogre, at the same time ogre moves towards Lady Irane. Ogre vanishes, as he is now standing on the same tile as Lady Irane does (this should proably initiate combat).

Lady Irane moves to an adjecant tile to pick up a treasure chest. Found treasure message pops up, and then Lady Irane is under attack. Battle is initiated. I doubleclick on the Ogre to get up his stat window, and the loot window from previous treasure chest pops up.

I click equip in that window, and FE crashed.

No savegame, since i hadn't saved yet.
