Nothing. The object isn't recognised by the targeting but will sometimes show its incorrect HP. Attacks do nothing either.
In this image I had smashed the crates, saved, quit, loaded and then did the same to the door behind it (attempting a workaround) which exacerbated the issue with an "undead" door. I could get the characters to climb atop the ghost crates as if they were in their original stack by "left click hold" movement. I could also get them to jump through the ghost objects by rotating the camera behind the destination (180° relative to the screenshot) and pixel hunting. Jumping this way wored rather tediously in both directions.
A common character portrait bug is also shown on Gale's icons. It's randomly triggered upon levelling-up.
