I just had an adventurer companion (chanter) lose all her equipped items too, beware. On the other hand I've also forgotten items in the quick slots without them disappearing when switching companions around.

This is certainly still happening, on a save created in 1.03 and only ever played in 1.03. Just drop an item in a follower's inventory, dismiss and recall that follower and the item is gone - it's not in the stash, any follower's inventory or in any of the Brighthollow chests.
