            Bug ID: 14823
           Summary: Thunar hangs when trying to disconnect from an sftp
                    connection that has been severed by a closed VPN
    Classification: Xfce Core
           Product: Thunar
           Version: 1.8.1
          Hardware: PC (x86_64)
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Medium
         Component: General

  Target Milestone: 1.8.3

Description: I have been forgetting to close sftp connections before closing
the lid on my laptop several times and the VPN tunnel closing causes Thunar to
become quite dysfunctional. This can also be triggered by manually closing
OpenVPN before disconnecting the sftp connection.

Steps to Reproduce: 
    Open a VPN tunnel
    Make an sftp connection to a server behind the VPN
    Close the VPN tunnel
    Try to close the sftp connection using the eject button

Expected result:
    Thunar should disconnect from the connection gracefully. A popup error
notifying you that that the connection was shut down unexpectedly would be nice

Actual results:
    Thunar hangs for several minutes before the timeout period finally frees
the process. A further problem is that after reopening the VPN, you are unable
to use the bookmarks you have made to that IP address and you have to resort to
manually entering it in the address bar
