interesting, so your hardware isn't lying then, unlike my USB sticks :-) So on that one you still get "eject" instead of "safe removal"? Can you confirm that you plugged this in _after_ starting your desktop session? As a heuristics for "hotpluggable" vs. "builtin" gvfs now only offers safe removal for devices which appeared during a running session, not for devices which were already present at boot.

If that's ok, can you please do "udisksctl dump > /tmp/udisks.txt" and attach /tmp/udisks.txt here? (After plugging in that USB flash drive)
