I've had that intermittently with my UI with the bags added as part of the map. As you say, having them open when you die and zone seems to be a common cause of the crash, but there also appears to be a more intermittent crash anytime you have them open when zoning.
For some reason crashes happen more often on some characters than others too, so I suspect it may even be down to the type of items / bags you have on you.
My workaround is this:

I've moved all my open inventory mods to the bandolier window. It means I can have them available at a keypress, but it's also easier to keep them closed most of the time, reducing the risk of a crash when zoning or dying. I've never had a crash while looting my corpse, and haven't crashed at all so far since using this mod.
Oh, and PS: It's designed from the start for clickies
