    Revert "Fix fr_application_local_command_line memory leak"
    
    This reverts commit 1139c1a6bc1707fdb64e8baa824d19b83c4ff835.
    
    The commit introduce a bug that prevent opening other archives
    when a file-roller window is already open.
    
    Steps to reproduce the bug:
    
    * open a Nautilus window
    * click on an archive -> file-roller shows the archive content correctly
    * click on another archive (without closing the first file-roller window) -> the new file-roller window is
    empty
