Status changed to 'Confirmed' because the bug affects multiple users.

[Philip Langdale (langdalepl)]

Assuming that the clean shutdown fix in 1.17.3 addressed this. Unplug problems are unpredictable and hard to reproduce, so I want to clean the slate and only look at reports from new releases with that possible fix.
