Perhaps I've found a simpler way to reproduce the issue:
Using nautilus, I dragged the only object in ~/Desktop (a folder) into ~/Documents.
Not yet sure if it's repeatable, but it might give insight into the trigger, if root cause is not already obvious.

Nope, not 100% repeatable with the nautilus drag - I just tried again & it worked w/o crash.
