It seems to be reproduceable, if I load a wider filearea with different filesystems (ntfs and ext4)

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

"Incomplete" makes sense to me because it appears the problem stopped happening after 3.28, and not at all in 3.30. We will need more time to verify that's really true:

https://errors.ubuntu.com/problem/87e4666825764619cb47f3837f871d88d65dd606

and if so then this is "Fix Released" already.

[Expired for gnome-shell (Ubuntu) because there has been no activity for 60 days.]

Zero crashes after 18.10 so consider it fixed.
