Summary: Deleting the last entry in the overrides tab in
                    winecfg is not shown correctly
           Product: Wine
           Version: 1.1.21
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Add multiple overrides on a clean .wine.

When the first entry (or anything but the last one) is deleted by selecting and
pressing "Remove" the new updated list is immediately shown.

When one tries to delete the last entry (multiple have to exist) the gui shows
that last one, and the previous one, highlighted. The list doesn't show that an
entry was removed. When pressing 'Apply' (or 'OK' and relaunch winecfg) the
list is updated and it indeed doesn't show the removed entry anymore.
