After latest upgrade, I am getting this spamming my logs when I use either nemo or nautilus to access files:
~/.local/share/gvfs-metadata directory has been cleared and rebooted with same issue arising.
gvfsd-metadata: g_udev_device_has_property: assertion 'G_UDEV_IS_DEVICE (device)' failed
PCMANFM does not cause this to happen it seems.
On github.com/GNOME/gvfs there is a new add which may be the cause?
