Description of problem:
I frequently have remote filesystems mounted from Nautilus via GVFS, specifically DAVS shares. If I put the host to sleep while remote shares are mounted and change my physical network connectivity (e.g. I unplug from physical network or move PC to different WiFi environment), upon resuming the host and attempting to unlock the screen the password seems to be accepted but the lock screen never goes away.

If I open a separate virtual terminal session and "killall gvfsd-http" then the lock screen disappears and my graphical session is accessible as normal (although the remote filesystem is now unmounted, as expected).


Version-Release number of selected component (if applicable):
Currently running gnome-shell-3.16.4-1.fc22 and gvfs-1.24.2-1.fc22


How reproducible:
The problem happens often, and the solution can be applied consistently.


Steps to Reproduce:
1. Connect to physical network port with remote filesystem share.
2. Log in to gnome-shell as normal user.
3. Open nautilus and mount a remote file share with a "davs://" URI scheme.
4. Observe the files are shown correctly.
5. Put the host to sleep via the gnome-shell menu.
6. Remove the physical network connection.
7. Wake the host and enter correct unlock password.
8. Observe the lock screen stays for several minutes (I assume indefinitely).


Actual results:
Cannot unlock gnome-shell session.


Expected results:
Should be able to at least get past the lock screen.


Additional info:
I have not tested this with other remote filesystem types (SMB, etc.) only with DAV mounts.
