Did you happen to have the terminal panel open showing the device at the time when you unmounted it?
Comment 2 BRULE Herman 2019-09-03 19:11:55 UTC 
I don't remember
Comment 3 Nate Graham 2019-09-03 19:15:25 UTC 
Can you get it to happen again by trying that?
Comment 4 BRULE Herman 2019-09-03 19:25:01 UTC 
I don't have the config to test this agains for now.
Comment 5 Nate Graham 2019-09-03 19:32:27 UTC 
Then there's no way we can debug the issue, sorry. :/

If you file a bug, you need to keep around the setup that caused the issue or else there's no way for us to help if we need more information.
