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
