This happens to me when trying to unmount an SMB share from Nautilus by clicking on the little triangular icon. However, when right-clicking and choosing "unmount", there is *no* crash.

This bug needs now to be notified to the upstream developers of GNOME (https://wiki.ubuntu.com/Bugs/HowToTriage#Forwarding_upstream).

Once this has been done, it will be ready to be worked on by a developer.

I can reproduce this issue with the following steps:

1. Open a Nautilus window. (It defaults to my home directory.)
2. Open a new tab or window. (This also opens to my home directory.)
3. In the new tab/window, navigate to a Samba share. (I have one bookmarked so I click on the bookmark in the left side panel.) A new entry for the share appears under Network in the left side panel.
4. Close the new tab/window.
5. In the left side panel, under Network, click the unmount icon next to Samba share entry.

At this point, gvfsd-smb crashes. I also get two alert boxes (I believe from Nautilus):

1. Oops! Something went wrong.
    Unhandled error message: The connection is closed

2. Unable to unmount <share name>
    The connection is closed
