Trying to undo a delete action using the ZMI, it spun for a couple of minutes and then produced the following traceback error:

The specific action I was trying to undo:

I think we decided that there were just too many changes since this one and undo was not possible. :(

@k2soule is this ok to close, wishing we could fix but can't?
