Bug details are below.
I could not produce the output of "parted DEVICE unit co print unit s print" because I had removed the flash drive thus device /dev/sdf was no longer present. Nevertheless, parted should not have produced a back trace and failed.

Did /dev/sde go away in the middle of this? There really isn't enough
info to go on here, but it looks like sde may have vanished and then it
tried to close a dev that was NULL (I'm guessing that was associated
with sde but without a reproducer it's hard to know for sure).
