Same problem here: Xubuntu 18.04, daily.
Mar 14 18:52:27 Xubuntu-18-04 gvfsd-metadata[1628]: g_udev_device_has_property: assertion 'G_UDEV_IS_DEVICE (device)' failed Mar 14 18:52:27 Xubuntu-18-04 gvfsd-metadata[1628]: message repeated 7 times: [ g_udev_device_has_property: assertion 'G_UDEV_IS_DEVICE (device)' failed]
In this case it's on a working install of 18.04.
Is there more information I can provide to help?
