After I unmount the camera from Nautilus, gThumb gives the same error. I get this from gvfs-mount:

22:33:41 [michael@tablet ~]$ gvfs-mount -l -i

    can_mount=1
    can_eject=1
    should_automount=0

After I eject the camera in Nautlius, I get the same error message, and this from gvfs-mount:

22:34:49 [michael@tablet ~]$ gvfs-mount -l -i
Drive(0): NIKON NIKON DSC E2100
  Type: GProxyDrive (GProxyVolumeMonitorGdu)

  is_media_check_automatic=1
  can_poll_for_media=1
  can_eject=0
  can_start=0
  can_stop=1
  start_stop_type=shutdown

Finally, after I choose Safely Remove Drive, I get this error message: "An error occurred in the io-library ('Bad parameters'): No error description available" and nothing from gvfs-mount regarding the camera.
