I got this bug when unmounting the fourth (and last) lvm volume on an external hd, and it seems like I can reliably reproduce it

I am not sure I can reproduce it, but I apparently got the same when ejecting/safely removing a SD card which was plugged into a USB multicard reader. Thought I had been doing the same before without seeing issues. When it happened the nautilus window seemed to go into a busy state for a while (greyed out).
